Description

The Church of St Fflewyn is a simple rural church featuring a continuous nave and chancel, a gabled southwest porch, a northwest vestry, and a west gable bellcote. It is constructed of rubble masonry with widely slobbered mortar, set on a plinth at the west end, and has a slate roof. The north and south walls contain paired rectangular leaded lights, while the southeast window appears to have been added to a blocked doorway. The east window is a round-headed arched window with two leaded lights. The porch has a round-headed arched entrance, and the inner door is boarded with broad crude hinges. There is a single leaded light in the north wall of the vestry.

The nave and chancel are combined under a roof with six bays, featuring exposed timbers and collared trusses. The chancel includes a simple squared moulded rail supported by stick balusters, with a pulpit and pews that have chamfered angles. At the west end of the nave, there is a plain 9-sided font dating from the 14th or 15th century.

The north and south walls display 18th-century slate memorial plaques. The north wall commemorates Richard, son of Richard Williams, who died in 1774, Arabella, wife of John Dreyhurst, who died in 1775, Richard Williams who died in 1796, and Jane, his wife, who died in 1779. The south wall features a plaque for Mary Vaughan, wife of Abraham Williams, who died in 1767, and Richard, son of John Broadhead, who died in 1781. Additionally, reset into the sill of the east window is a fragment of a gravestone with floriation and an inscription, partially illegible, beginning: HIC JACET MADOCUS ... This fragment is medieval, dating no earlier than 1300.
