Garden walls and gazebo at Bryneithyn Hall

The garden walls and gazebo at Bryneithyn Hall are constructed from high uncoursed rubble with a slate capping. The walls enclose a roughly circular area that is approximately 100 meters in diameter, with the main entrance located to the northwest, flanked by tall square piers that likely date from the mid-19th century.

Attached to the north side of the wall is a two-storey circular tower made of rubble stone, topped with a shallow conical slate roof that was renewed in the 20th century. The upper storey features a west-facing door accessed by a flight of stone steps against the inside garden wall, which has replaced a set of unsupported stone slabs that used to project from the curve of the tower, most of which are now broken. There is a small window on the upper floor's northwest side with 20th-century glazing. Additionally, there is a French door on the south side of the upper storey that once provided access to a timber platform, which is now rotted. The ground floor has a boarded timber door on the north side.
