Old St Peter's Church is a small but important survival from Peterhead's earlier history, standing with its burial ground close to the old settlement core. The ruined church gives the town a visible medieval anchor, contrasting with the harbour, fishing industry, and later granite streets.
It is a short stop rather than a long visit, but a worthwhile one if you are walking Peterhead's older quarters. The weathered stones and graveyard make the town's age more tangible and help balance the more modern maritime character of the port.
