Church of St Decumanus

The Church of St Decumanus is a largely medieval building, with substantial additions and alterations from the 19th century and later. It is constructed of rubble stone with slate roofs. The church comprises a nave, chancel, southeast chapel, north transept, a south tower over the south transept, a southwest vestry, and a north porch. The chancel and transepts are irregularly aligned. A prominent, tall Pembrokeshire tower features a corbelled parapet and 17th or 18th century obelisk corner finials. The tower has small, plain bell openings – two to the east and west, and one to the south. A 2-light window was inserted into the south side during the 19th century. A southwest stair tower rises in five shallow steps.

The nave shows evidence of blocked windows, likely related to the tower’s construction. A blocked, unmoulded pointed south door is present, alongside a small 1869 2-light window above it. A gabled southwest addition is visible, believed to represent a small oratory that replaced a former south porch. 19th-century features include the south window, a cross-gabled chimney, and a west door. The west end of the nave has battered angles and a large 1852 3-light window, incorporating older voussoirs. The north porch is a large, vaulted structure with a wide, rounded arch, a gable with reset carved shields and a carved angel (said to have originated from Angle Church), and adjoins the north transept, which features a small 19th-century 2-light window. The east gable of the nave has a sanctus bellcote. A squint, with a 19th-century 2-light window, connects the transept and chancel. The chancel has a 19th-century 2-light east window, with evidence of gable repairs to the end wall. The adjoining southeast chapel has a 19th-century 2-light east window, two 19th-century 2-light windows on the south side, and a buttress.

The north porch contains a fine, square, scalloped font, dating from the 12th or 13th centuries and originally from Pwllcrochan. A pointed north door features a tiny carved medieval figure of the Risen Christ above, discovered on a nearby farm. The nave has a 5-bay 19th-century roof, a small, whitewashed late Norman font, a north-side tomb recess, patterned glass in the west window, and two commandment boards. A fine baroque monument, dating from 1716 and belonging to F Powell of Greenhill, is located within the nave. The south window contains glass by H Hughes of London, dated 1880, while a 1869 timber pulpit and lectern are also present. Corbels flank the transept openings to the west. The chancel arch is plastered. The north transept features a plastered stone vault and pointed stone arches leading to the transept and south tower. The transept has tomb recesses on the west and north sides, and an inscribed tomb slab in the west recess. A richly carved base of a 15th-century monument or shrine, adorned with quatrefoil decoration, is situated between the north transept and nave. The lower chamber of the tower is vaulted, with a southwest door. A segmental arch connects to the southeast chapel, and a damaged stone bowl, possibly a quern with a square rim, is also present. The chancel has a 19th-century roof, a mid-14th-century recess with remains of cusping and side finials, two plastered arches to the southeast chapel, an octagonal centre pier, a damaged piscina in the south wall, and a recess in the east wall. The southeast chapel includes corbels on the north wall, a 19th-century roof, two south wall tomb recesses (one containing a carved 14th-century female effigy), and two medieval coffin lids reset on the west wall. An ogee pointed piscina is located on the south wall. A plaque commemorates WáMeares of Eastington (d1768), while a 19th-century altar and pulpit, also from Pwllcrochan, are also present. The east window, dated circa 1960, is by Celtic Studios. The southwest vestry has pointed arched recesses on the east and south walls.
