An ancient and derelict church on the island of Gigha (Argyll and Bute), St. Catan's Chapel (also known as St Cathan's Chapel, Kilchattan Church or Gigha Old Parish Church) is situated in the shadow of a mobile phone mast a half-mile (1 km) south southwest of Ardminish. The rubble shell of a small chapel remains, now B-listed. Featuring two lancet windows, the chapel dates from the 13th C. but fell from use in the early 18th C. A Latin cross is carved on the left side of the lancet window in the gable wall. Limited repairs were undertaken in the 19th and early 20th C, but significant conservation work was undertaken in 2010, including consolidation, repointing the walls with lime mortar and capping the wallheads with clay and turf to reduce deterioration. St. Catan was an Irish monk who built a foundation on Bute in the 6th C. and nearby there was a holy well also dedicated to the saint, but its precise location is now lost.
It is surrounded by a kirkyard which includes several grave slabs from the 14th and 15th centuries. These include representations of animals, swords and scrolls, one with an effigy of a Highland warrior. Other memorials date through until the later 19th C., with a modern graveyard adjacent.
