[1] The priory of St. Mary and St. Martin is one of the oldest examples of Norman architecture in the country.

This priory was founded by Roger de Builli of Tickhill Castle, one of William the Conqueror's followers.

It was staffed at first by monks from the Mother House, Holy Trinity Priory at Rouen France.

In 1286 Thomas Russel had to be returned to Rouen because of his intolerable conduct and also John de Belleville, as the climate did not suit him.

(equivalent to £130,000 as of 2023),[2] After the Dissolution the east part of the church was demolished and a tower built at the west end of the nave.
