The outer curtain and its rounded angle towers are now very ruinous, but the outer gatehouse is well preserved. This is actually just a gateway flanked by open-backed, half-round towers. It is curious that machicolated parapets crown the towers but not the gateway.

The inner courtyard is reached through another gatehouse flanked by rounded turrets. Keyhole gun ports appear here and elsewhere in the walls. To the right of the gatehouse, the curtain is embellished with alternate panels of stone and flint, creating a checkered effect. The corner tower here has vanished, but the round towers at the other three corners, along with much of the intervening curtain, still stand. These towers were machicolated as well. Within the courtyard, the only domestic feature to survive is a vaulted undercroft, which carried the solar.
