Old St Peter’s Church, Thurso Travel Guide

Old St Peter’s Church stands as a testament to Thurso’s deep historical roots, with origins tracing back to at least 1220, and possibly as far as 1125 or earlier. Founded by Gilbert Murray, Bishop of Caithness, the site may have been a Norse graveyard before the church was built, evidenced by runic stones found on the grounds. The church’s early structure included a stone rectangular building with a tower offset to the south of the chancel, reflecting medieval ecclesiastical architecture and Norse influences in the region.

Over the centuries, Old St Peter’s Church underwent significant modifications. A north aisle was added in the 1500s, later expanded with an upper storey. In the early 1600s, it served as a replacement cathedral for the Bishops of Caithness after damage to Dornoch Cathedral, prompting the construction of a large south aisle featuring an ornate south-facing window—the church’s most striking surviving element. The tower, originally housing three bells recast into one in the 1740s, was also used as a prison, complete with jougs (iron collars) to hold offenders. Above the chancel, a room served as a courthouse, highlighting the church’s civic as well as religious role.

By the late 18th century, structural issues led to the church’s replacement by a new building in Thurso, with the last service held in January 1833. The roof was removed later that year, leaving the church a roofless ruin for nearly two centuries. Remarkably, its stone walls have never been quarried for building materials, preserving the integrity of the ruins. The surrounding burial ground contains gravestones dating from the 17th and 18th centuries, featuring carved skulls, crossbones, and emblems representing the trades of the deceased.

Old St Peter’s Church is a category A listed structure of national importance, once acting as a proto-cathedral for Caithness and a focal point for the local community. The site embodies the layered history of Thurso—from medieval Christian worship and Norse heritage to its use in civil justice. It also holds intriguing local lore, including a memorial to Reverend William Munro, who reputedly encountered a mermaid nearby. Today, the church is maintained by a local preservation association and remains a poignant symbol of Thurso’s past.

Situated in the heart of Thurso near the River Thurso and Thurso Bay, the church ruins offer a peaceful yet evocative atmosphere.
