Seven Dials Covent Garden is a unique quarter of London whose star-shaped layout remains as constructed in the early 1690s. It was brought back to life largely through the dedication of the Seven Dials Trust, working in partnership with the local authorities and landowners for nearly forty years.

Opened in 1753, Aldridge's Horse Bazaar or Repository for Horses and Carriages was a famous horse mart, located close to Long Acre which was famous for its carriage and coach building and ancillary trades. During the mid 19th century there were accusations of insider dealing and the proprietor advertised many auctions with the statement that 'under no circumstances is the practice of misrepresenting the ownership of horses ever resorted to.' In 1895 it was described  as 'especially famous for the sale of middleclass and tradesmen's horses'.

The last horse sale was held in 1926, but by then there had also been many greyhound sales, and motor cars had been sold there from as early as 1907.  Aldridge's closed in 1940 and the buildings were demolished in the 1950s.
