Borough Market 250th Anniversary

11am: The Town Crier heralds the ceremonial arrival of the Lord Mayor and a day of 18th-century revels.

The market trustees invite traders and customers to don 18th-century dress; the best child's costume will win a cake from Patisserie Lila and £150 to spend in the market (result to be announced in front of the entrance to Roast at 3pm).

2006 is also the 400th anniversary of the Worshipful Company of Fruiterers who will be bringing superb fruit to Borough.

All afternoon street performers, actors and musicians in period dress will mingle with the crowd to take Borough Market back to its beginnings in 1756.

Roast will serve 18th-century dishes and host family workshops given by a team from Tate Britain on Hogath's Southwark Fair, kindly loaned by Southwark Council.
