Petticoat Lane Market
By 1608 this street was known as Peticote Lane for the second-hand clothes, etc. which were bought and sold here, right on the boundary with the City. In about 1830 the street name was changed to Middlesex Street but people still talk of Petticoat Lane Market.
Currently the market consists of two adjacent street markets: Wentworth Street Market (Sunday - Friday) and Middlesex Street Market (Sunday only). Which means if you want to go pavement plaque-hunting the only sensible day is Saturday.
See Spitalfields Life for some photos of the market in its heyday.
