Gordon Cooper Library, housed within Convocation Hall, won the Heritage Trust Building Award in Nova Scotia for conserving its exquisite architectural features, which include Romanesque windows, stepped buttresses of the Decorated Gothic period, dentilled cornices of the Classical Revival era, and small interior columns and a hammer-beamed ceiling reminiscent of medieval English churches of the Norman period. This grand stone edifice accommodates an eighty-foot oak ceiling, spiral iron staircases, carved plaster corbels and a small stage for public speaking and debating competitions.
