Description
Nos. 1 and 2 St. Mary's is a house constructed from random multi-coloured rubble with freestone dressings and features Welsh slate roofs. It showcases Gothic details typical of a standard vicarage design and consists of two storeys and an attic. The elevation facing The Cathedral Green has two bays. The left bay has a projecting gabled section with a 2-light attic window, pointed heads, and a trefoil above. On the first floor, there is a paired trefoil-headed window separated by a colonette, and on the ground floor, a 3-light flat-headed window with pointed arches above. The right bay facing The Cathedral Green includes a gabled attic window with two trefoil-headed lights and taller paired trefoil-headed windows on both the first and ground floors. The house has a steeply pitched roof with two tall stone stacks, although the right corner has been altered to include a mansard roof and rooflight. The elevation facing Heol-fair features two projecting bays with gables at the south-west end, trefoil-headed and pointed windows, and a single attic window. Towards the north-east end, there is a porch with a pointed head and a corbelled external chimney. The interior was not seen during the resurvey.
