Reginald Theodore Blomfield

Rye, East Sussex, was the home of the architect Sir Reginald Blomfield who was responsible for three significant designs that commemorated WW1: The local hospital, the Cross of Sacrifice and The Menin Gate in Ypres. A bronze sword which hung in the hall of Sir Reginald Blomfield’s home in Rye became the inspiration for the town’s wartime memorial - the Cross of Sacrifice. The design was adopted by the Imperial War Graves Commission and widely used in Britain and abroad.
