Pottery Lane

From the longer Wikipedia page

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.
