What Remains

  • Two-thirds of the fort walls remain at their original height of 30 feet, and enclose 10 acres, making it the largest of the Saxon Shore forts.
  • The fort was unusual because it was more of an oval shape than the usual rectangle. This was probably due to the shape of the raised land it was built upon.
  • D-shaped towers project from the walls at regular intervals. These are a feature of later Roman forts.
  • There are two gates – a large West Gate which was the main entrance, and a smaller arched East Gate.
  • Large Norman Keep and medieval walls within the fort.
