The rebuilding of the Church is a milestone in the history of one of the oldest Christian communities in Warwick. Its exact foundation date is lost in the confusion of the 17th-century Civil Wars. It certainly existed by 1649 and was probably started by soldiers of the Parliamentarian army. It is the oldest continuing Baptist church in Warwickshire and possibly in the whole of the Midlands.

Castle Hill Baptist's History is a long one:
