Heritage Open Day: St Mary's Church is a beautiful and ancient Grade I listed building, dating from approximately 1200 when the present chancel was built, although there is evidence of a church as early as 1086, including the font, which is used today. When the Doomsday surveyors came to Marston in 1086, they found a new church, which was probably a simple rectangular building in stone with a thatched roof and was built by the priors of Tutbury who held the Manor of Marston under Henry de Ferrers. The only visible remains of this church are the font, which is now situated in the Bell Tower, and the top of a window, used in the building of the North Aisle.
