Church of St Mary, Letchworth

Mentioned in the Domesday Book of 1086, parts of the building date to the 11th century and is built on the remains of an older Saxon structure.

The church has a pyramidical timber-framed bell-cot with a tiled roof at the west end inside which is a bell dating to the 14th century.

The exterior is of flint and ironstone random rubble, partly rendered, with freestone dressings and ashlar, brick and tile buttresses.

Inside there is a carved effigy of the Crusader Sir Richard de Montfichet on a window sill.

In 1908 a "mission church" dedicated to St Michael was opened on Norton Way South, closer to the new town centre.
