 Opened by the Duke of York, the future King George VI of the United Kingdom, DGSB is one of few state school in Britain to have a working organ, which is housed in the Great Hall and leaves for Hamburg every 25 years for expert care and maintenance.During World War II, the school building was requisitioned and used by the Royal Navy as a station for WRNS with pupils and staff evacuated to Ebbw Vale in south Wales.A notable feature of the school building is a large stained glass window showing St. George and bearing the names of past students of the school who fell in World War Two with a separate memorial to students in World War One.
