Baynard's Castle

Baynard's Castle refers to buildings on two neighbouring sites in London, between where Blackfriars station and St Paul's Cathedral now stand. The first was a Norman fortification constructed by Ralph Baynard and demolished by King John in 1213. The second was a medieval palace built a short distance to the southeast and destroyed in the Great Fire of London in 1666. According to Sir Walter Besant, "There was no house in [London] more interesting than this". The original castle was built at the point where the old Roman walls and River Fleet met the River Thames, just east of what is now Blackfriars station. The Norman castle stood for over a century before being demolished by King John in 1213. It appears to have been rebuilt after the barons' revolt, but the site was sold in 1276 to form the precinct of the great priory of Blackfriars.
