Abbey Gatehouse

The Abbey Gatehouse is part of the Premonstratensian Abbey of St Agatha, dating to the early 14th century. It is constructed of sandstone rubble with ashlar dressings. The building is two storeys high and has three internal bays.

The north-east facing gable end has pilaster buttresses with splayed, chamfered plinths that terminate in a roll. A semicircular arch is set within a double-chamfered pointed arch, beneath a label with head stops, rising from three responds with Early English capitals displaying nailhead decoration. A continuous sill band appears around the corner buttresses. Above, a two-light pointed window features Y tracery, with two side trefoils and a pointed quatrefoil at the top. Two water-chutes drain the inserted roof at first-floor level. A blocked two-light window is set within the gable, featuring a flat stiff-leaf in the blind spandrel. The gable is coped.

The south-west facing gable end mirrors the north-east, with buttresses and a sill band as previously described. The arched opening is similar to the north-east, but without nailhead decoration. A two-light pointed window with a quatrefoil in the tracery is positioned above, also with a label incorporating head stops.

The north-west side has pilaster buttresses at each end. A doorway opening is present at the inner (right) end. Rough stonework indicates the former location of external steps providing access to a first-floor chamber. On the south-east side, in addition to the end buttresses, two further buttresses are centrally placed. A blocked central doorway and another at the inner (left) end are quoined, both with segmental-pointed heads. A single-light, chamfered window sits centrally on the first floor. A corbel table is present.

Inside, a cross wall separates the outermost and central bays, featuring chamfered semicircular openings. The larger opening corresponds to the carriageway, while a smaller opening serves as a postern opening, both with labels. Three bays of quadripartite vaulting are present, with chamfered ribs bearing masons’ marks and rising from Early English corbels. The inner faces of the responds’ capitals display leaf-stops with entwined stems, with each design unique. Chamfered segmental rear arches are evident to both the inner and outer archways. Blocked doorways oppose each other within the central bay, while opposing chamfered pointed doorways are found within the innermost bay.

The gatehouse features a cross wall with chamfered semicircular openings, and a vault with chamfered ribs rising from Early English corbels. It is considered to be the best preserved monastic gatehouse in Yorkshire. It is scheduled as an Ancient Monument.
