St Cynhaearn's Church

The church is dedicated to Cynhaiarn, a 5th-century saint. It was originally the parish church for Porthmadog. Its nave dates from the 12th century, and the north transept was added in the 16th century. The south transept was built in 1622. Most of the interior fittings are Georgian in style and date from 1832. It came into the care of the Friends of Friendless Churches in 2003, since when repair work has been undertaken.

It is constructed in stone rubble, with the walls of the nave and the east side of the chancel being stucco. The roofs are of modern slates. Its plan consists of a short nave, north and south transepts, and a short chancel. At the west end is a bellcote. The entrance is through a west door. The windows in the nave and transepts have two lights, and at the east end are three lancet windows. The interior is plastered above a timber dado. The floor of the body of the church is stone-flagged, and there is a painted floor in the sanctuary. At the west end is a gallery.
