Description

The Church of St Justinian is a Grade II* listed building constructed of rubble stone with slate roofs. It features a nave and chancel that are nearly equal in length, a south transept, and a west bellcote. The building has coped gables and a windowless west end. The small gabled bellcote includes stone voussoirs around an arched bell-opening. There are two north windows with stone voussoirs and small-paned sash windows that were originally 12-pane. The south door of the nave is plain and boarded, with Preseli stone voussoirs. The south transept has a broad low gable and a pointed broad south window with a small-paned sash window that has Georgian Gothic glazing bars, along with a slate-hung gable. A squint in the angle to the chancel features a straight diagonal wall and a slate roof.

The chancel is built with rough masonry and has narrow windows on each side with oak lintels and small-paned timber glazing with arched heads. The east window has a timber lintel, timber glazing, and a stone sill, with a square head and an arched leaded light. Inside, the church has whitewashed plaster walls and red small quarry tiles on the floors. The nave contains five 19th-century collar trusses with wishbone struts above the collars. There is a low pointed plastered chancel arch with rough imposts on the piers, and a corbel on the south wall to the right of the south transept arch. The south transept features a whitewashed plastered pointed stone vault that is approximately 3 meters wide and 2.5 meters deep, with a broad squint passage on the east wall leading to the chancel. The squint has a plastered vault and a rough impost on the left side, with an asymmetrical arch into the chancel.

The long chancel has a utilitarian pine roof with exposed undersides of slates, and long windows on each side with timber small-paned glazing. The east window has a square-headed reveal with an arch-headed leaded light in a timber surround. There is a medieval square font with a shallow rim and conical underside, along with later 19th-century plain pews and a plain 19th-century panelled timber pulpit. The sanctuary has a single step and cast-iron 19th-century scrolled standards for the rail. The east window features a square head with timber framing, and the glazing is arch-headed with coloured leaded panes.
