Description

The Priory is a house of 15th-century origin, significantly altered in the 16th and 17th centuries, with a north wing added during the 17th century. It was formerly a long property connected to No. 15. The building is rendered, with a pantile roof. It has two storeys and originally contained two principal window bays. To the left is a two-storey bay with four-light, moulded mullion casement windows; the windows have elaborately moulded sills and cornices. To the right, on the ground floor, is a four-light mullioned and transomed window, and a bay window with a moulded sill. A central six-panel door is sheltered by a porch. A plank door is present on the left side of the building. A two-storey rear wing is also part of the property.

The interior features a hall with a chamfered stone fireplace and a square head. The hall retains stop-chamfered beams. A parlour is characterized by panelling made of small square and rectangular panels, and contains a dog-leg staircase with turned balusters. The Great Chamber, formerly known as the Chapel room, has an arch-braced collar beam roof with two rows of curved windbraces. A chamfered stone fireplace, with a shouldered head and moulded mantel shelf, is also present. A fragment of wall-painting is visible to the right of the fireplace, depicting a Maltese cross within a circle and a coiled snake. A spice cupboard with scratch mouldings on the door is located further to the right. It is believed the building was originally an ecclesiastical building.
