Art fan Tony Podesta traveled to Rome….

Their travelling, and the knowledge of the global art scene they have acquired, has turned them into two of America's best-known collectors. They were meant to be in Rome on vacation when I caught up with them. But the day before they had been out ferreting in Trastevere, where they found a couple of Wolfgang Tillmans photographs, which they unwrapped with engaging enthusiasm.
They are known for purchasing "awkward" works, such as video installations, that many other private collectors will not consider. "It's easy to store them, but difficult to display them," says Podesta. To get round the problem, he and his wife have excavated a huge subterranean vault beneath their house outside Washington - a white space 5m square and 4m high in which it will be possible to show "very complicated video pieces" on all four walls.
