These windows are pointed and cusped, and a broad cusped transome divides them in their height. The angles of this story are splayed, and it is finished with a new plain parapet resting on a simple corbel course. The tower is surmounted by an octagonal spire of the stunted kind common at this time, and with a very marked entasis. It is divided by two string courses in the height, and has two tiers of lucarnes.

It forms in appearance the interior of an apse with five sides, elaborately carved with minute niches and recesses, and is covered with vaulting (now broken). This apse is spanned by a moulded and pointed arch carried on clustered shafts. Beside these, and over the arch, there is a succession of niches and figures, interspersed with tall much subdivided windows. Unfortunately this monument was greatly damaged by the fall of the roof, which occurred last century. According to tradition six splendid silver maces were found within the tomb, one of which is preserved in the college, and the others were distributed amongst the other Scottish universities.
