Description

The Ucheldre Centre, formerly known as the Bon Sauveur Convent Chapel, is a building constructed from grey-green stone with pale stone dressings over an inner concrete core, topped with grey-green slate roofs. It features a Romanesque apsidal plan, low aisles, flanking vestry blocks, and a saddle entrance tower. The exterior includes simple round-arched openings along its six bay sides. The saddle tower has parapetted gables, twin-arched openings with shafts and linked hood moulds, and a tall single light with twin nookshafts positioned between clasping buttresses. Above the three-order doorway, there is a blind arcade. To the left of the tower, there are three arches leading to a service block with a long return in grey stone; the doorway is flanked by groups of three round-headed windows, and towards the rear, two windows feature seven narrow arched lights. A modern block with a hipped roof is located at the rear. To the right of the tower, an arched screen wall in exposed stone connects to Ty’n Parc.

Inside, the undivided space consists of six bays with a concrete tunnel vault and a semi-dome at the apse, featuring half-shafts to the transverse ribs. Full-height arched bays interpenetrate the main vault, and there are single clerestorey lights above the segmental aisle openings. A timber gallery is situated in front of the tower arch.
