The parish church, on the north side of the marketplace, is dedicated to St Andrew. There is some masonry surviving from the thirteenth century, but the nave, north aisle, choir and tower are late fourteenth century, built of random rubble and flint. The clerestory dates from the early sixteenth century, and the south aisle was rebuilt in brick in 1824. Adjacent to the church is the old school building of the Tudor period, Enfield Grammar School, which expanded over the years, becoming a large comprehensive school from the late 1960s.
