The Chapel

The Chapel is a 19th-century building constructed from squared grey rubble stone, featuring sandstone quoins and yellow-brick dressings. It has a steep slate roof with coped shouldered gables, stone cross finials, and crested ridge tiles. Designed in the Gothic revival style, the chapel has simple side walls with three tall 2-light windows framed in yellow brick and a yellow brick chamfered plinth. The northern end wall is rendered, while the southern end gable includes a yellow-brick louvred opening behind an elaborate porch-cum-bellcote. The porch mirrors the gable's line on a smaller scale, with a yellow-brick pointed arch at the front and small lancets on the side walls. Above, there is an oversized bellcote made mostly of yellow brick, resting on stone corbels at the front, featuring an arched bell-opening and a steep slate-coped gable. The doors are ledged with ornate hinges.

Inside, the chapel has ledged pointed inner doors and a 3-bay roof, with rendered walls lined to resemble ashlar. It contains pitch pine pews and a quarry-tile floor, with pine benches flanking the pulpit at the northern end. The pulpit, an extraordinary piece dated 1875, appears to be constructed from salvaged carvings. It has five canted sides with a moulded cornice and large pointed, shouldered panels, with the framework adorned with metal flowers. The front panel features what looks like a Baroque picture frame, heavily carved with an arched head and cherubs leaning on trophies above. The picture-panel has been replaced with wood, displaying the date 1875 in raised numerals. Other sides of the pulpit seem to incorporate re-used 17th-century panelling, with 19th-century leaf carvings above. A hanging iron candelabrum is present, and a plaque on the southern end reads, "This chapel was built by Lord Newborough for the inhabitants of Bardsey Island in the year 1875." Below the plaque is a floral wreath.

Within the chapel, there are two incised stones. One features the lower part of a cross with a ring-knot and interlace, along with the lower half of a carved figure above, and an undeciphered inscription on the left side reading '-esilli mar: queno', likely dating from the 10th or early 11th century. The other stone, inscribed with a cross, dates from the 7th to 9th century and was discovered built into the Hendy barn.
