There’s an area so desirable that the masters of the universe are snapping up islands and peninsulas there. The new, must-buy or must-visit place for the richest men on earth is the Ionian. So it’s bye-bye to St Trop, Tuscany and the Hamptons and hello to Meganisi – an Ionian island where there’s no tourist infrastructure and which only even got mains water and electricity in the Eighties. Are you surprised that that’s where the super-wealthy are going?

Well, listen up. If you already own enough camels, Chelsea barracks, Qatar and Al Jazeera, what would you spend your oil money on next? Ionian islands, naturally. In May, the emir of Qatar bought six islands just two miles from Ithaca. (Remember your Homer? Incidentally, Ithaca is also where designer Marc Newson is building a house.) The Sheikh’s islands include Oxia – roughly 20 nautical miles from Meganisi and the largest is 1200 acres – and cost a mere £7.35 million. They’re uninhabited and he fell upon them when he moored his superyacht nearby.

In April 2013, Aristotle Onassis’s granddaughter, Athina Onassis Roussel, sold a 99-year lease on Skorpios – another private island in the Ionian Sea. It went for a snip at £100 million – fortunately the lavish pink villa that the late shipping buhzillionaire Aristotle Onassis built for Jackie O and the nearby islet of Sparti were also included in the sale. The happy purchaser is Ekaterina Rybolovleva, 24, daughter of Russian billionaire businessman Dmitry Rybolovlev. (The potash man/owner of AS Monaco FC who has a fortune estimated by Forbes at $9 billion.)

British billionaire banker Lord Rothschild also caught the bug for the region by holidaying in Kensington-on-Sea, as his bit of Corfu is now known. Now he’s snapped up 8km of Meganisi – roughly 3500 acres of a peninsula – and the neighbouring 200-acre island of Kythnos. Roman Abramovich and sculptor Anish Kapoor are both keen to build homes on Lord R’s Meganisi estate. Enough said. You can’t get cooler than Kapoor.

History is repeating itself. Onassis could have bought anywhere in the galaxy – and snapped up Skorpios. Niarchos bought Spetsopoula, a small island off Spetsai. Fifty years later, the diamond-encrusted wheel has turned full circle – this little spot in the Ionian is turning again into the epicentre of the jet-set world.

Now Tom Hanks, Spielberg, Abramovich, Bill Gates and Madonna cruise its waters on super yachts – the £200,000 to £700,000-a-week type. Little wonder. It’s one of the lovelier places in the universe (or certainly Europe) for sailing.

And what of Meganisi, the place that Lord R has selected as his little bit of paradise? (Or Tafion as the island was known in the Odyssey.) It’s where Aristotle Onassis visited in the Sixties, alongside Maria Callas, Winston Churchill, and Jackie O – who went for ouzo and appetizers at the local tavernas in Vathy.

Go to Meganisi and you’ll find a place lost in time. You’ll reach it by boat from Nidri, passing Skorpios on the way. It’s small (just 9 sq km) with just 1041 inhabitants. It is little developed and is home to a lot of sheep and olive trees. Not hooked yet? Ah, but you will be.

The island is as naturally beautiful, secluded and unspoiled as it gets – one of the great and untouched parts of Greece. There are pebble beaches and ones like finest sugar crystals and waters so clear you can see forever, hidden bays and enough privacy to deter even the most determined paparazzi. There are wild green valleys, steep cliffs honeycombed with caves only accessible by boats, secret coves and ooh-ah views from the top of Lord R’s peninsula over to the mainland. The locals are also incredibly friendly – call it ‘philoxenia’ (friendliness to strangers)….they do.

The most wow! villas weren’t available before for rental. But because of the crisis, top properties are coming onto the open market. Alexandros Matsukis – director of Ionian & Aegean Island Holidays and market leader in renting out villas on the sort of islands on which the big boys have set their sights – is picking up the best. His villas currently have locations that would turn Zeus green with envy, with panoramic views over the endless sea and direct access to almost-private beaches. Book for next year, and Matsukis will be offering ones with splendid interiors, great quality builds and fabbo infinity pools too.

So get there. Go sailing on the aquamarine sea. Take out a speed boat. Whizz around the narrow traffic-free lanes. Sit in a taverna sipping Retsina. See for yourself why Giorgio Armani, Bill Gates and Madonna have been scrambling to buy in the region. And why party time is coming there again.

This is the story of the Marquess, the Old Masters and the Bentley. The tale of my bravely blazing the trail for masterpieces by Van Dyck, Rubens and Murillo to be returned from Russia to Norfolk 234 years after Catherine the Great bought them in a sale that caused national outcry in Britain.

It’s a story of me and my trusty Mulsanne intrepidly leading the way from the Hermitage State Museum, St Petersburg, across thousands of miles of frozen terrain to Houghton Hall, Norfolk – and there, in their original home, the grandest of stately piles, to await the arrival of the priceless collection of paintings that was originally housed there and belonged to Britain’s first PM, Sir Robert Walpole. Except I cheated a little.

Reader, I had planned to do this long drive (1868 miles behind the wheel through Latvia, Lithuania etc.). Honest. But then to circumvent a billion-hour wait at the Estonian border crossing, monotonous days of unspectacular scenery of the northern European plains and USSR-size piles of bureaucratic papers, I took the plane from St Petersburg and then drove from Heathrow to Houghton.

So instead this is now a far more thrilling story – about the car made in Heaven and finished off in Crewe: the Mulsanne. After all, who needs to read about endless roads, blizzards and Russian forests when you could be thinking about a vehicle with TVs in its headrests and veneer tables for champagne flutes?

So we can pass quickly over the W hotel in St Petersburg with its clientele of Russian twigs in spray-on dresses. There! Done. And gloss over the joys of that city’s grand apricot palaces and orthodox churches by the frozen Neva River on which people were walking. We need also reflect only fleetingly on my private visit to the Hermitage – with its three million Michelangelos, Picassos etc. – a breathtaking place where it would take 11 years to see everything, spending just one minute before each exhibit.

Indeed, the only really important thing about St Petersburg was that I was chauffeured in a Mulsanne. Twice when we stopped in the city, passers-by gawped at and photographed our palace on wheels. You think it’s cor! from the outside – well, you should be in here, I wanted to cry. It glides, it purrs and it smells so good I want to bottle it (leather and veneer); there are acres of seats – ones that massage/warm to perfection and probably serve vodka; vanity mirrors for applying that slick of Dior lipstick; soft- shut doors; and a Bentley designed phone. That’s Russia done then.

We can also dispense hastily with British sights, including my stupendous private visit to the fine Palladian house that is Houghton. And forget my meeting with the 7th Marquess of Cholmondley – its current occupant, the country’s most important peer and who has secured 70 of Sir Robert Walpole’s best pictures back from Russia. And disregard the William Kent décor there being returned to its splendid original 18th century specifications.

All that matters is that I drove to Norfolk in a Mulsanne. A motor that goes nought to seriously fast in a nanosecond; with suspension better than any bed; and boasting special specifications – like polished aluminium wheels (£13,410) and sunroof. When I rested a while, I had at my fingertips its bespoke silver tumblers and ashtrays. And a Naim for Bentley sound system. Quite some trip. But with this car, every journey is an event.

Alexandros Matsukis, director, founder, co-owner of Ionian & Aegean Island Holidays, provides a close-up of the region. His tour operator company has been renting out villas there since 2002 and is now the undisputed market leader on the sort of islands for which the big boys are gunning.

Ionian & Aegean Island Holidays have 200 villas on 10 islands and mainland Greece on their books, including several private Matsukis- owned properties, and a turnover of £9 million and growing annually. They have offices in London, Lefkada and Meganisi.

Is this little spot in the Ionian turning into the new epicentre of the jet-set world?
Some of the richest and most powerful men on the planet are buying here. The Emir of Qatar has just bought six islands including Oxia; one of the world’s richest Russians, billionaire businessman Dmitry Rybolovlev has scooped up an island, Skorpios; and in the middle of them, in Meganisi, billionaire banker Lord Jacob Rothschild has bought 8km of land and a small island.

You’ve said that history is repeating itself in the region.
The late shipping billionaire Aristotle Onassis could have chosen anywhere in the universe. What do you do when you own most of Monaco and have billions in gold reserves? Choose Skorpios as your haven, of course. Niarchos – his big rival and another one with all the money and influence in the world – bought Spetsaipoula, a small island off Spetsai. 50 years later, the wheel’s turned full circle – and the most powerful people on the planet are choosing this area again.

For lesser mortals, what if Greece blows up or things get tougher – despite its having been bailed out?
The worst is over. We entered the tunnel first and so can see the light at its end earlier, certainly before Spain or Italy. In Greece the austerity was harsh. People were so worried – but now you see a look on people’s faces of hope and acceptance. We’re quite philosophical. After all, we invented philosophy.

But austerity means that even the rich are now needing to earn extra money by renting their villa, doesn’t it?
The most beautiful villas in the area were never before available for rental. But because of the crisis and the new taxation, even the wealthy are suddenly needing to meet more bills and bring in more money – so a lot of top villas have now come onto the open market. We’ve picked up 25 of them in the last two years. They’re mostly wealthy Athenian’s second houses – summer homes – and investments.

The standard in the rental market has jumped hugely over the last couple of years. A few wealthy Greeks who’ve owned small private islands for decades are also putting them on the market after the government increased property taxes and stretched them too far.

So the new luxury heralds the end of billionaires needing yachts, does it?
The area has been a massive draw for the ultra wealthy for years. They visit in the summer on mega boats – from Hollywood A listers like Tom Hanks and Spielberg, to Roman Abromovitch, Bill Gates and Madonna. The emir of Qatar moored his super-yacht nearby for a holiday. Because there isn’t yet the luxury on shore, they use their own private gin palaces – the £200-700,000-a-week type. But with the new developments in the region, they’re soon going to be able to do luxury on shore.

How are Ionian & Aegean Island Holidays keeping up?
We’re keeping apace of local developments by moving into the luxury market aswell – currently we offer simple to 5*. We’re investing in and improving properties that have settings from paradise – all in incredible locations with sea views and often with direct access to deserted beaches – but whose owners haven’t previously added luxurious décor and fittings.

By offering the owners longer contracts – say three years on a property with exclusivity – we’re getting them to invest more. We’re repositioning ourselves in the region as a luxury product too for clients who want a notch above the rest. Next year, we’ll be able to offer amazing infinity swimming pools, great quality builds and interiors, space and panoramic views. But we’re not talking super luxury.

What are your views on the area going upmarket? On the jet -set coming to land? Party time coming to the region again?
You’ve got the wrong idea if you think it’s going to be party town. You’re more likely to come across parties for patron saints of the islands or a festival to honour the archbishop…. a service in a tiny church followed by free wine, soup and sardines outside plus music and dancing. But it’ll be plain sailing for serious investors like Rothschild. There’s more than enough natural beauty to create something amazing here. All he has to do is design some interesting properties.

There’s a lot going on in the travel business in the region, isn’t there?
There has been fresh interest in the area. Upmarket operators Think Ionian – as in Think Sicily and Think Puglia – have just started here. (They too are going to be running a new weekly charter flight here.) But we’ve already contracted all the best villas since Travelux stopped operating here. The big operators don’t bother with places like Meganisi or Paxos, small islands that are much harder to operate on and are more costly because of boat transfers etc. We have our own boats.

What’s the future look like?
On Meganisi we have thirteen villas and are building two more (at the cost of the owners). Since 2011, we’ve been adding 20 per cent more properties to their portfolio a year, and 50 per cent more in Meganisi alone.

Are you now going into partial ownership?
We’re looking at buying properties with investors. We want to invest in Greece (rather than just contracting) because of the bargains and our commitment to the country.

If you’re not Greek, it’s known to be difficult to do business there. People can be put off by Greece’s red tape and inefficiency, can’t they?
It’s a lot easier these days, foreign investment is very welcome and a lot of the hurdles and red tape has ended. After the last few years of the Troika, the coalition government has simplified Greek laws and made the country as inviting as possible for foreign investment, seeing the importance of growth in addition to austerity. Foreigners like Lord Rothschild will sometimes still get Greek business partners to use as ‘frontmen’ to speed up local processes, but it’s really not necessary these days.

And if you’re buying an island?
Ithaca’s Greek-American mayor, Ioannis Kassianos recently said: ‘When you buy an island, even if you are the emir of Qatar, it takes eighteen months to complete the paperwork.’ But it’s a well-known secret that exceptions can be made for investors of that calibre.

The mayor felt that development plans could also pose problems and that the emir may be set for a long battle with Greek officials over his plans. Regardless of the size of the land, a home can be no bigger than 250 square metres. ‘The emir,’ said Mr Kassianos, ‘responded to that suggestion by saying his WC is 250 square metres.’ But I think the emir will get his 1,000 sq metre loo if he wants it!

You’ve dug deep into your piggie bank and are very committed to the region, aren’t you?
Ionian & Aegean Island Holidays take in four planes weekly from Gatwick, Manchester and Birmingham. As an operator, we’re the most exposed locally, but our clients can always get flights.

What does Lord Rothschild know that we don’t? Why would someone want to buy/rent on Meganisi?
It is not a Corfu or Rhodes, even though Lord Rothschild has an estate in Corfu. Islands like Meganisi don’t even have scheduled international flights. Most operators and purchasers went to Kefalonia, Lefkada, Corfu and Rhodes. Luckily Meganisi has been forgotten. It’s a secret paradise – as naturally beautiful, secluded and unspoiled as it gets – and uniquely peaceful. But it didn’t have the properties to begin with. It’s smaller. (Just 9 square miles.) It kept going quietly with its old, loyal visitors.

The mentality of the people there takes you back in time. They’re quite different, not greedy. They open their homes to visitors, and offer them hospitality. Their attitude to ‘philoxenia’ (friendliness to strangers) surpasses that of any other island. The competition it has faced from neighboring islands has been a blessing in disguise. It’s been a victim in a nice way.
