Built during the reign of King Henry III by Berenger Le Moyne this elegant, large rectangular castle near Oundle was encased by a high curtain wall flanked by huge two storey towers, its walls being over 12 feet thick.
During the English Civil War it was used by its owner, Sir Edward Montagu, as an arsenal for the Royal cause. After the Civil War, the Montagu family built a substantial manor house, Barnwell Manor, near the castle. That branch of the family which became the Earls of Peterborough are commemorated in the village church in a series of fine tombs.
The castle remains a private residence.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 10/06/2023. It remains the responsibility of any pilot to check for any changes before flying at the same location.
