St Duthus's Collegiate Church, Castle Brae, Tain

St Duthus Collegiate Church dates to the 14th century. It was re-roofed in around 1752 and later restored by Robert Matheson between 1849 and 1882 with further work carried out by Hippolyte J. Blanc in 1896.

The church is a rectangular 4 bay buttressed building with a stepped base course. The entrance is on the southwest with shafted reveals under pointed hoodmoulds with sculpted head label stops.

The church has a tall Y-tracery west window with flanking cupsed niches set high in the gable wall, the most northern panel has a figure of a bishop. There are lancets in the north walls under pointed hoodmoulds. The tall east window has renewed geometric tracery. There are three large windows in south wall, two with Y-tracery and that to the south-east with geometric tracery.

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

There is a rubble retaining wall around the graveyard, with late 19th century spearhead railings to Castle Brae.
