Description

The Tower of St Hilary's Church is a square, three-stage embattled structure, standing approximately 14 meters high. It is built of limestone rubble with green and red/brown sandstone dressings. The west entrance features a pointed arch with an inner arch and a continuous moulding that lacks capitals. This entrance contains a ribbed, boarded door, likely from the 16th century, although it has undergone some restorations.

The second stage of the tower has single lights on the south and north faces, while the bell stage is adorned with paired, arched windows that include horizontal wooden slatting. At the top, there is a crenellated parapet above a simple string course, complemented by straightforward projecting sandstone gargoyles.

Additionally, the west gable of the nave remains intact and includes a blocked four-centred arch leading to the tower.
