Description

Chygrysys is a Wesleyan chapel that was later used as a Sunday School and has now been converted into a private house. It was built in 1795 and was enlarged, altered, or rebuilt in 1836, as indicated by a datestone. The building is constructed of stone rubble with granite dressings and features a slate roof with a hipped end at the front.

The overall plan is rectangular. Originally, it included stables and a store on the ground floor with a meeting room above, accessed by an external flight of steps at the front. The two-storey elevation facing the road has a central stone rubble and granite flight of steps with an iron balustrade that leads up to the entrance. The steps are set forward, and there is a plank door to the store beneath them. To the left, there are 19th-century plank double doors leading to the store and stable.

On the first floor, there is a central entrance with likely 19th-century double doors, flanked by two horned 36-pane sash windows, also probably from the 19th century, which contain some crown glass. Above these windows, granite lintels have been extended to create a continuous granite string band below the eaves. Directly above the entrance is a carved relief of a bust of John Wesley, dated 1836, created by local sculptor Nevil Northey Burnard, whose birthplace is commemorated by a plaque on the adjacent cottage. The interior was altered when the building was converted into a house in the late 20th century.
