The gatehouse was built by John de Haudlo in 1312 and is all that remains of Boarstall House, a fortified manor house that was demolished in 1778. Although it was updated in 1615 for use as a banqueting pavilion or hunting lodge, it retained its mediaevalbelfry, cross loops and crenellations. The exterior and many rooms are essentially unchanged. The property is tenanted with limited opening arrangements. Exterior rooms remain virtually unchanged since 1615.
