In 1924, to ease lorry traffic congestion around Covent Garden Market, this section of Monmouth Street became one of the first roads in London to be made one-way. The Crown public house has been trading on this spot since at least as long ago as 1700. It bears the date 1833, when the pub was rebuilt. No.21, part of the venerable French restaurant, Mon Plaisir, which opened in the 1940s, is one of the surviving buildings built by Thomas Neale and contains original panelling.
