Beyond the cellarage some 2 metres below the square's surface adjacent to Carvers cafe are the remains of an apparently domestic well which had a surprisingly fine sandstone "collar" or coping. A brick-lined drain runs past it which is similar to others excavated on the site. These drains are apparently associated with attempts at land drainage prior to the construction of Dudley Flint Glassworks. Judging by the pool of water that collected here the drain is still in good working order.
