History

Former parish church, now maritime museum. Built c1825-7, on site of former church whose registers date from 1694. A church was established here in C5 by Nefyn ar Nefain, daughter of Brychan Brycheiniog of Garth Madryn. The name was recorded as Llanfair-yn-Nefyn in C12 when the church was held by Augustinian Canons of Haughmond Abbey. In C13 a priory was attached to the church. The rebuilding in 1825-7 cost £370, the churchwardens were Robert Williams and John Roberts, their names and the date are etched on the bell in the tower. Improvements costing £200 were made in 1856 and it is probable that the N porch was added at this time when the original doorway in the W wall of the tower was converted into a window. In 1904, a second church, St David's, was opened in Nefyn. However, St Mary's remained the parish church until 1912 and a Sunday School was held there until c1960. The church was subsequently converted for the Lleyn Maritime Museum which opened in 1979.
