High Quality Content by WIKIPEDIA articles! St Mary`s Church, Pentraeth is a small medieval parish church in the village of Pentraeth, in Anglesey, north Wales. The date of construction is unknown, but is probably from some time between the 12th to 14th centuries. A church dedicated to St Mary was recorded here in 1254, but there is a tradition that there was an older church dedicated to St Geraint, an early British saint. Some medieval stonework remains in three walls of the building (the west wall, and parts of the north and south walls). A chapel was added to the south side in the 16th or 17th century. The church was altered and refurbished during the 19th century, including an extensive rebuilding by Henry Kennedy, the architect for the Diocese of Bangor, in 1882. St Mary`s is still used for worship by the Church in Wales, and is one of five churches in a combined parish. Its conservation is specifically included in the aims of a Chester-based charity that promotes health and the arts in Anglesey and the north-west of England.
