Capel Trisant

Capel Trisant is a chapel with unpainted rendered walls and a slated roof featuring bracketed eaves. It has a prominent gable front with brackets at the verge, two large arched windows at the center, which have 20-pane glazing and Gothic intersecting bars in arched heads. There are two plain square-headed outer doorways with board doors. A slate arch-headed plaque in the gable reads 'Capel Tri Saint a adeiladwyd yn y flwyddyn 1820 a ail adeiladwyd yn y flwyddyn 1850'. The right side wall includes two square-headed 24-pane sash windows, while the rear wall has two similar sashes and overhanging verges at the gable. The left side wall features one similar window behind an attached range.

Adjacent to the chapel is a low rendered house or vestry range with a slate roof and a stone stack on the ridge to the left. This two-storey structure has a board door to the right, a 12-pane sash window to the left, and a small pair of casement windows on the first floor left under the eaves. The rear has a pair of casement windows above a small 12-pane sash.

Inside, the chapel does not have galleries. It features painted grained raked box pews arranged in three rows, with inward-facing pairs of pews on each side and a single pew in front of corner panelled timber lobbies, each with one pew attached facing the pulpit. The pulpit was removed in 2004. The ceiling is flat and includes a plaster rose.
