St Baglan's Church, Llanfaglan, stands in an isolated position in a field some 150 metres from a minor road. The size of the surrounding churchyard and the presence within the structure of the church of a stone dating from the 5th or 6th century is evidence that an earlier church or churches stood on the site. It is traditionally credited to its namesake, the 7th-century saint Baglan ap Dingad. The present church dates probably from the 13th century. The chancel was rebuilt in about 1800, when the north porch was also added. Unusually, the church escaped restoration during the Victorian era, and so its interior is still little changed since about 1800.
Describing the reasons for its Grade I listing, Cadw states it is 'a rare example of a medieval church unrestored in the 19th century, so retaining an exceptionally complete set of 18th-century furnishings'.
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).
