St Duthus's Collegiate Church, Castle Brae, Tain

St Duthus Collegiate Church, located on Castle Brae in Tain, dates back to the 14th century. It was re-roofed around 1752 and underwent restoration by Robert Matheson from 1849 to 1882, with additional work by Hippolyte J. Blanc in 1896.

The church is a rectangular building with four bays and buttresses, featuring a stepped base course. The main entrance is on the southwest side, showcasing shafted reveals beneath pointed hoodmoulds with sculpted head label stops.

Prominent architectural features include a tall west window with Y-tracery and flanking cupsed niches set high in the gable wall, with the northern panel depicting a figure of a bishop. The north walls contain lancet windows under pointed hoodmoulds, while the tall east window has renewed geometric tracery. The south wall features three large windows, two with Y-tracery and one in the southeast with geometric tracery.

Inside, the church boasts an elaborate oak pulpit with a tester, which is a late 19th century restoration incorporating fragments of the original 16th century pulpit. There is a triple sedilia in the southeast under a cusp recess, a cusped stoup near the center of the south wall, and a long round-headed aumbry in the southeast corner of the east wall. The interior also includes numerous memorials, such as a marble classical monument to Arabella Margaret Rose, created by Williams, Sculptor, of New Road, London. A tomb niche in the north wall houses an early recumbent figure. The stained glass windows were made by James Ballatine and Sons of Edinburgh in 1880 and 1882.

Surrounding the graveyard is a rubble retaining wall, complemented by late 19th century spearhead railings along Castle Brae.
