The church of St Benedict's no longer exists. It originally stood on the north side of the Queen's Head Inn (44 High Street), which itself also has gone. A part of the churchyard remained well into the 20th century but all has now been built over.
The church was granted in the time of Henry I to Huntingdon Priory by Rodbriht, the Deacon of Huntingdon, and is one of four mentioned in the Papal confirmation of 1147 to the Priory. The fabric suffered much in the English Civil War, but the tower remained standing "very ruinous and useless" until 1802 when it was taken down; some parts of the foundations of the church still remain. There are frequent bequests for the repair of the church in Wills of the late 15th and early 16th centuries.
A plan to unite the parish with St. Mary was set on foot in 1656, and in 1661 was finally approved by Royal Warrant.
