 In 1936 former pupil Harold Whitlock planted an oak tree sapling in front of the entrance to the Gymnasium which he had received, along with his Gold Medal for the walk, from Adolf Hitler at the Berlin Olympic Games.By 1955 the school had 620 pupils and 32 staff, resulting in a necessary extension on the east side of the main building, which included a new Hall, Dining Hall and Kitchens.This was officially opened in 1961.
