Date1909 - 2006LocationConcrete BlockDescription"A" Block was also called "Administration Block" or "Concrete Block", depending on the decade it was in use.
The first part of A Block was built in 1909, which included four classrooms. It was enlarged in 1913, which included a further three classrooms and a Science Room. By 1930, three Science laboratories were added and in 1968, a Language Laboratory was built. It was used as classrooms until 2006 when it was demolished to make room for the new Common Rooms , although the old north gable end with its Bishop’s Mitre and ‘Diocesan High School’ inscription have been preserved for incorporation into future developments.
