Used originally as a Chapel of Ease to St Andrew's Collegiate Church in Cotterstock, St Leonard's was in 1923 united with St Mary the Virgin, Southwick. A further change was the inclusion of St Mary the Virgin, Benefield during the 1980s. Links with Southwick were severed in 2000, this time Glapthorn and Benefield joining the Parish of Oundle with Ashton.

Much of the building dates back to the12th C, although the porch and south doorway were added in the 14th C. There are also traces of medieval wall paintings, probably of St Christopher, patron saint of travellers.

During the reign of James I the alter rail and panels in the pulpit were installed. Other noteworthy items are a Victorian bier, used for funerals, and an original pew located at the back of the church, three bells and a fine organ.

Worship, the focal part of church life, takes place weekly, but this lovely old building also hosts concerts, flower festivals and is a venue for the local Primary School for key events in the Christian calendar.

Today as part of a much larger Benefice our aim is to promote growth in faith, widen our horizons and above all nurture the love of God.
