Llanthony Priory

Llanthony Priory consists of the remaining ruins built from local red sandstone ashlar and rubble, showcasing much of the original carved work. The ruins include the entire church ground plan, much of the west end, the walling and entry below the west window, and both towers which rise in three stages. The north nave arcade with triforium, the west wall of the crossing tower, a significant portion of the south transept, a small part of the north transept, and varying heights of walling at the east end are also present. The north and south aisles have mostly disappeared. It is noted that the nave was likely unroofed in 1504, though it is unclear if this means it never had a roof or if it simply lacked a vault and had a timber roof instead. To the south, there is a vaulted entry to the cloister (slype) and the base walling of the Chapter House.

The surviving structures display two distinct architectural styles. The east end and transepts are Transitional, dating from around 1175 to 1200, with a grant for this work from Henry II. The nave and west end are in the Early English style, dating from around 1200 to 1220, while the Chapter House is from the mid-13th century and reflects a later Early English style.

Design features include two-storey elevations, arched windows framed by Romanesque colonnettes at the east end, and typical lancets with multi-shafting at the west end, where the West Country style is particularly evident, including concave-backed niches. The north arcade is continuously moulded. The nave consists of six evenly spaced bays west of the crossing, followed by two wider bays leading to the west front. The colonnettes in both the nave and Chapter House have waterholding bases, and the Chapter House features a five-order recessed entrance. The only remaining vaults are a two-bay rib vault in the eastern entry (slype) and in the undercroft of the Prior's Lodging, which is now the Abbey Hotel.
