Description
The Clock Tower is a High Victorian Gothic three-stage square tower with a spire, open at the ground floor. It is constructed of snecked grey rubble with cream-colored freestone dressings on most of the top and bottom stages. The middle stage features freestone quoins and diagonal bands of Mansfield Red stone. The tower is topped by an octagonal crocketed spire with a stone finial and an iron weathervane, rising from the square bell stage, which has corner tourelles, each adorned with its own iron finial. Below the clock faces, there is a foliated cornice and implied machicolations. The staircase below has narrow, stepped Gothic lights. At each corner of the base, griffins are seated on small marble colonnettes. The lower stage has a splayed out design with a fishscale and crenellated cornice. Each side features a tall gable with heavily foliated finials and roundels displaying heraldic emblems. The arches have hoodmoulds and rosettes, with impost bands and unpolished marble colonnettes, along with inner cusping. Diagonal buttresses with gables and miniature tower-like pinnacles are also present. The tower stands on a stepped platform, and the open ground floor has a quadrapartite ribbed vault.
