This Tudor country house was built around an early 13th century nunnery. It was given by Henry VIII to Richard Cromwell in 1538 at the time of the Dissolution. Queen Elizabeth I came here and King James I was a regular visitor. The next owners, the Montagu family, soon to become the Earls of Sandwich, also played an important part in British history and the House remained their ancestral home until the 1960s when it became a school housing the 6th form. Hinchingbrooke School was formerly Huntingdon Grammar School which, on the site of what is now the Cromwell Museum in Huntingdon, was attended by Oliver Cromwell and Samuel Pepys.

The House provides facilities for weddings, balls, dinner dances and conferences and is open to the public during the summer months.
