The medieval St Leonard's Church dates mainly from the 15th century, although there are traces of much earlier work. It is a relatively large, "townish" church by Essex standards. The church also stands at an important road junction, contrasting with the familiar Essex pattern of a church and manor house complex on the same site. These features are consistent with John Blair's formulation of an Anglo-Saxon minster, in contrast to a private oratory in its origins, and the place-name would perhaps suggest Cedd's mission at the Chapel of St Peter-on-the-Wall near Bradwell (to the north) as its parent.
