San Lorenzo is a Baroque-style Roman Catholic church building in Melfi. The octagonal church was initially built in the 1000s by the Byzantine rulers of the city, and was soon occupied by canons belonging to the nearby Abbey of Monticchio. In 1500, it became a parish church.
The church has suffered damage over the centuries from the earthquakes. The present portal and long stairs appears to date to the 17th century. The adjacent bell-tower, rebuilt in the 14th century by the family of Niccolo Acciaiuoli, has since collapsed, and only the base remains. In 2015, the church underwent refurbishment including demolishing a parish house built to the left of the entrance portal.
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).
