Marston Grade I listed Anglican parish church is dedicated to St Mary, and is of 12th-century origin, with an 1881-82 chancel by C. Kirk. Pevsner gives the date of the chancel as 1878, restored and partly rebuilt in Early English style. St Mary's holds monuments to members of the Thorold family.
Marston Hall is a Grade II* late 16th-century country house, with further alterations up to the 18th century. Pevsner records a 1962 "gothick" style garden gazebo, designed by John Partridge, with pinnacles by Christopher Blackie and murals by Barbara Jones.
The village has a church, a hall, the Old Barn Hotel, the Thorold Arms public house, a fishery, and the Marston Thorold Primary School. The school, still somewhat supported by the Dame Margaret Thorold Educational Foundation, is now Church of England voluntary aided. The building dates from 1861.
