Chapel of St Mary to N of Vaynol Old Hall

A rectangular aisless building aligned NW-SE. Rubble masonry with quoins and a slate roof, a crucifix on the E gable. Gabled porch to the SW not bonded in, has a depressed arched entrance and dated keystone (WWE 1596) and stone benches either side. Turned timber balusters form the upper part of the porch walls. The inner doorway has broached stops. Three-light windows with arched lights and hollow-moulded jambs under a square head and label. A similar 4-light window is set in the E end.

Exceptional marbled enrichments carried out in the conversion to a family chapel in 1910. The walls are fully lined with marble, and the floor is of black and white chequered marble, all in a richly Italianate manner. Sixteenth century arch-braced roof trusses and chamfered purlins. Some C16 glass survives in the stained glass windows. Altar with kneeling angels at either end. Wall monuments to the Assheton-Smiths at the W end, set within ogee-headed recesses, and plaque reading "completed and restored by him [Sir Charles Assheton-Smith] and his loving wife Sybil Mary"; the former died 24/9/1914 and the latter 27/10/1943. Balustraded steps lead down to a single-chambered and similarly marbled mausoleum with coffins to either side of a central passage.
