De Keyser's Royal Hotel was a large hotel on the Victoria Embankment, at its junction with (now the A201), Blackfriars, London. The location was formerly the site of Bridewell Palace. The Royal Hotel was founded before 1845 by Constant de Keyser, an immigrant to England from Belgium. It was a high-end hotel, catering mainly to visitors from continental Europe. His son Polydore de Keyser ran the hotel from around 1856. Sir Polydore de Keyser had no children. His hotel was sold to a limited company in 1897, and a nephew Polydor Welchand de Keyser took over the management.
