1778 AD
The Chapel of the Keep is used as a beer cellar.
By the end of the eighteenth century, the castle was in a state of extreme disrepair and bore very little resemblance to a defensive structure. Mr Fife, landlord of the Three Bulls’ Heads was using the chapel as a beer cellar, a confectioner had dug an icehouse out of the wall in the south-west corner of the Keep, and a currier had a workshop elsewhere in the building. The roof of the Keep was being used as a cabbage garden. There were also proposals to erect a windmill, and convert part of the building into a brewery, but when no tenants could be found, those ideas were dropped.
1810 to 1812 AD
Newcastle Corporation purchases the remains of the Castle and begin its restoration. The Corporation bought the buildings, including the Keep, from John Turner for 600 guineas. Alderman Foster was put in charge of the restoration. During the same period, the Moot Hall was built on the site of the former Queen’s Mantle, with an approach road on the south side of the Keep. The building work destroyed parts of the medieval castle and many of the houses in the Garth.
