Capel Beili Heulog

Capel Beili Heulog is a chapel built of painted rubble stone, featuring a slate eaves roof that overhangs at the gables. It is a single-storey structure with a gable end entry, which includes double three-panel doors topped by a cambered brick head, and a nine-pane window with an iron lintel to the right. The side wall has three nine-pane windows, with one positioned centrally above and the other two at ground floor level on either side. The rear of the chapel has late 19th-century render and two added long casement-pair windows with cambered heads.

Inside, the chapel has a whitewashed plastered interior with a deep gallery at the entrance end and enclosed stairs to the gallery located to the right of the doorway. The square newels support the gallery, which has a flat underside and a brown-painted front panel that features vertical panels arranged in three sets of six. There is a moulded top rail. The pews are arranged in two blocks and painted in two shades of brown. Two benches are positioned on each side of the broad space in front of the pulpit, which has a panel front and a bench below. The balusters on either side of the pulpit are chamfered but stop just short of the midpoint, creating a square boss, while the corner posts are turned with rings. There is also a bench seat behind the pulpit.

Memorials within the chapel include one for William Williams of Llethertiley (died 1812), made of painted slate with elaborate incised scrolls and signed by Jones; another for Elizabeth Pugh of Pengrythin (died 1848), featuring a draped urn with a red-painted border, signed WW of Erwood; and a memorial for William Pugh of Pengyrthin (died 1825), crafted from slate with a marbled border surrounding an oval plaque, adorned with spandrel rosettes and signed by Price of Builth.
