Before the belfry, is a stepped circular base made of granite. At the corners of the campanile, seated and supported by this circular base are the Higher Faculties represented in four deceptive figures of Divinity, Science, Medicine and Law sculpted from portland stone by Irish sculptor Thomas Kirk. The belfry is a cylindrical chamber encircled by Corinthian columns, between which are tall, round-head traceried windows with cast iron grills. The base of the belfry also has four carved coats of arms at each side, almost directly above the carved keystone faces below. Each coat of arms faces out onto a prominent location in the college, and symbolize strong connections it had with external forces. Over the belfry are two domes which are covered in decorative scale-patterns. The first is the larger of the two and has carved scrollwork ribs that continue vertically from the columns of the belfry. The smaller dome sits directly above the larger, commonly referred to as a lantern rather than a dome.
