Pottery Lane is a street in Notting Hill, west London. Today it forms part of one of London's most fashionable and expensive neighbourhoods, but in the mid-19th century it lay at the heart of a wretched and notorious slum known as the "Potteries and the Piggeries". The slum came to the attention of Londoners with the building of the Hippodrome in 1837 by entrepreneur John Whyte. Unfortunately for Whyte a public right of way existed over his land and "dirty and dissolute vagabonds" from the nearby slum invaded his race-course, adding to his financial difficulties and, in part, leading to the closure of his venture in 1842. Pottery Lane gradually improved in the late 20th century along with the rest of the Notting Hill area, and today the houses sell for seven figure sums.
