The Anglican parish church at Mareham-le-Fen, Lincolnshire, is dedicated to St.Helen. The lower stages of the tower, which is embattled and crocketed, and the windows of the north aisle suggest the late 13th century whilst the chancel and chancel arch dates from the early 14th century.The church was 'drastically' restored in 1873 when the 14th-century chancel was almost entirely rebuilt. Further restoration work was done in the late 1960’s and early 1970’s.
