12th Century motte and bailey castle constructed on a raised mound of earth surrounded by a defensive ditch. Before the surrounding marshland was drained in the late medieval period, the castle would have effectively sat on an island. Pedestrian gates were installed at the site in 2023 due to damage caused by off road motorbikes. Unfortunately, they aren't working, there were plenty of tyre tracks in the mud all over the hill in October 2025.
