Description
The Church of St Ceidio is a simple rural church built in the mid-19th century, following the plan of a 14th-century original. It features a continuous nave and chancel, constructed from rubble masonry with freestone dressings. The modern roof is made of large thin slates arranged in diminishing courses, with stone copings and a dressed stone bellcote.
Entry to the church is through a 14th-century doorway located at the west end of the north wall. This doorway is round-headed with chamfered jambs. The windows on the north and south walls are 19th-century paired trefoil-headed lights set in rectangular frames, including a single window to the left of the north doorway and two windows in the south wall. The east window, dating from the late 14th century, is a single light featuring simple tracery within a two-centred head and a hoodmould. Additionally, there is a kite-shaped recess at the apex of the west gable.
Inside, the church has a four-bay roof with exposed collared trusses that extend down to wall posts resting on plain corbels. The furnishings are 19th-century, including simple bench pews and a raised pulpit adorned with trefoil-headed facing panels. The chancel is elevated by one step and has a moulded rail supported by stick balusters with cusped brackets. On the north and south walls, there are 18th-century marble memorial tablets: one commemorates John Griffith of Ceidio, who died in 1753, and his wife Damaris, who died in 1751; the other honors Dorothy, wife of the Rev. John Lewis, who died in 1763, the Rev. John Lewis himself, who died in 1783, and three of their children.
