The Church of St Mary the Virgin is the parish church of the village of Nash. The large church is medieval in origin, with additions and restorations dating from the 18th and 19th centuries.
The church consists of three parts. It has a three-story 15th-century steeple with an octagonal spire, but provides no access to the body of the church. The nave is 18th-century and the chancel 19th-century. The interior has a complete Georgian ensemble of gallery, box pews and three-decker pulpit.
The only remains of the Norman church is the North Wall of the chancel and the squint or hagioscope. An unusual feature, the squint was used to enable those with leprosy, smallpox or other such diseases, to see or participate in the service without endangering the rest of the congregation with infection. The tower is unusually located on the north side of the chancel. The church is thought to originally have been much larger, incorporating a North aisle.
In the early years of the 20th century the floor of the bellringer's room was used as a temporary mortuary for the bodies of five sailors who had been drowned at sea, in a violent storm, near the East Usk Lighthouse. Four of the sailors had been found lashed to the mast. During World War II the church saw congregations of 400. In the fields to the south of the neighbouring Church Farm are ancient tumuli, the vestiges of some ancient, possibly mediæval, dwelling or chapel.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
