The lake to the N was developed out of a fishpond in 1841 by C R M Talbot. It is likely that the culvert and the wall containing the archway are contemporary.


Open stone-lined culvert with flat stone coping. Water enters the N end under a round arch of narrow voussoirs. This arch is part of the N boundary wall of the castle gardens, and the top of the wall rises over the arch in the same semi-circular profile. At the S end of the culvert, the water passes underground under a high flat-headed opening. Adjacent to it on the E side, a few stone steps lead down from the S, with a pump located within a small square enclosure to the E.
