Basing House Ruins: The remains of the Basing House, once the country's largest private house and the palace of the powerful courtier William Paulet, Marquess of Winchester. The earthwork banks of the castle still dominate the ruins. The wealth and power of the Paulet family, their loyalty to the crown and nearness to London brought disaster to Basing in the Civil War. After long sieges and bombardments the House fell to Oliver Cromwell in person.
