With 210 auctions every year offering more than 65,000 lots, Christie's in South Kensington is one of the busiest salesrooms in the world.

A bewildering array of amazing things get sold here: from Fabergé eggs to Medieval manuscripts, rare wines to Old Master Paintings.

Plus, you can now take along your old bits of bric-a-brace to get them valued by the experts free of charge. A bit like The Antiques Roadshow, except of course you don't get to go on the telly.
