Church of St. Peter

The church is oriented slightly S of E, and consists of a nave with chancel under one roof and a S aisle of almost equal height and width. There is a N transept and a S porch. The church is built of uncoursed masonry in limestone and gritstone. Steeply pitched slate roofs, with crested ridge tiles and coped gables to the nave cum chancel and porch. Plain ridge tiles and pointed roof verge to the aisle. There is a conspicuous C19 bell turret at the W of the nave. C19 buttress(es) in line with the internal arcade.

Some small early windows survive, mostly blocked: a square-headed window to the N transept; a very small square-headed opening at the N of the chancel, close to the transept; in the same wall, further E, a high-level pair of trefoil lights; and in the S aisle wall, a pair of small, high-level windows with four-centred arches, roughly repaired. The other windows of the church are C19, of Seddon's restoration, in Decorated style: two trefoil-headed lights with trefoiled roundel above. The E window is of three lights with a larger ornate top roundel. Seddon's eye-catching bellcote over the W wall of the nave terminates with four steeply pitched gables.

The arcade is C13 or C14 in character, but restored by Seddon, and consists of five arches. It has circular columns with simple mouldings and caps of cushion type. From the nave there is a step up to the chancel and another to the altar. The nave and chancel roof is of ten bays with arch-braced collar-beam trusses. The S aisle roof is of common rafters with crossed collars. The N transept, which houses the organ, has a canted timber ceiling and the porch has common rafters with collars.

The nave floor is of limestone flags. In the chancel and sanctuary there are Minton encaustic tiles, including a reredos. C19 pulpit against the N side and C19 pews. The choir stalls have carved fronts. Gothic carved altar on a white-painted plinth, plain timber altar rails.

There are four stained glass windows, including the nave W window, a South Africa war memorial of 1900.

The church has a good collection of mural monuments, including, against the S wall: an early C17 chest-tomb memorial to the Philipps family of Lampeter Velfrey parish, with no lettering but four heraldic displays; a Baroque monument in yellow limestone with broken and open pediment, with cherubs' heads, damaged; a memorial to the Rev. Edward Philipps, rector, 1793, in the form of a white marble sarcophagus-end on a black marble ground, erected by Mary Dorothea (his daughter), relict of Nathaniel Phillips of Slebech; a white-marble memorial to Richard Willy of Treffgarne, 1807, within a black marble surround of pilasters, shelf, brackets, entablature, with low-relief draped urn at head.

The font is square, tapered beneath, on a square pillar, with a black slab step.
