St Mary Magdalene Church stands a mile or so from Great Hampden Village. Its isolation made it an attractive location for some scenes in the 1970 film Cromwell. In more modern times Hampden House was used extensively by the Hammer film studios as the perfect gothic backdrop for many of their films.
The nave of Little Hampden Church was built in the 13th Century and a distinctive half timbered porch was added in the 15th century. There are 13th century wall paintings of saints inside that were discovered in 1907, however they are incomplete due to a major rebuild of the chancel in 1859. Opposite the church is Manor Farm which is white plastered.
