Church of St Leonard

Wren's Cathedral, properly the Church of St Leonard and now a cathedral of the Communion of Evangelical Episcopal Churches, was originally the Lady Chapel of Wroxall Priory.

Wroxall Priory was founded in 1141 as the Priory of St. Leonard for nuns at Wroxall, Warwickshire by Sir Hugh-Hatton, eldest son of the Earl of Warwick. He fought in the Crusades and was released after being held prisoner for seven years in Jerusalem and having a vision of St. Leonard, the patron saint of prisoners. He so appreciated the intervention of the saint that he gave 3,000 acres of land to the church in Wroxall to form a monastery for nuns after the Order of St. Benedict which was named the Priory of St. Leonard at Wroxall.
