 The school originally had its home at 100 Watergate Flags, an 18th-century house built upon the site of an extramural Roman bathhouse.Once again, the Duke of Westminster supported the school by offering the trustees a piece of land which had once been the site of Chester's City Gaol and House of Correction, together with a gift of £500 towards the building of a new school.This site, right on the city walls of Chester still exists today as the home of the school's senior pupils.
