Boxgrove Priory

The Priory was founded in the reign of Henry I, about 1123[1] by Robert de Haia (or de la Haye), Lord of Halnacre by gift of the king.

The Priory was founded for three Benedictine monks, and was a dependency by the Lessay Abbey in Normandy.

[2][3][4] In about 1126, upon the marriage of Robert's daughter Cecily to Roger St John the number of monks living at Boxgrove was increased from the original three to six.

A 19th monk was added to the priory in about 1230 by William de Kainesham, Canon of Chichester.

At the time of the dissolution there were eight priests and one novice, as well as twenty-eight servants and eight children living in the priory.
