Tanners Hall  Tanners Hall was a 13th century town house and is now a ruin located on Gouda Way in Gloucester. It is the oldest non-religious building and only surviving medieval domestic stone house in the city. It became a Grade II listed building on 29 July 2015. Tanners Hall was originally a medieval merchants house built in the 13th century. It was taken over by Tanners in 1540 and was used as tannery until the 18th century. Excavations of the site have revealed evidence of 17th and 18th century tanning pits. In the late 18th century, the ground floor was divided and part of it was constructed with bricks and mortar. In another part of the building, a hearth area for a vat was built. In the mid-19th century, it was converted into two cottages with brick wall constructed to separate them. Additional supports for an upper floor were built and one of the ground floor windows was converted into a door. The western part of the building was used as a paint shop at this time. The building fell into disrepair during the 20th century and it was abandoned until it was rediscovered in 1976 as Gouda Way was being built. At some point a southern doorway and steps to a first floor hall were added as these were found when the site was excavated in 1983. Between 1913 and 1918 the area was used for vehicle repair, with the hall and cottages being gutted out and converted to garage buildings. During the 12th and 13th centuries, most houses in Gloucester were built with timber-frames and as such were susceptible to damage by fire. However, Tanners Hall was one of the few structures at this time to be built entirely of stone, with parts of it having survived until the current day. It is now a ruin consisting of just three walls and some remnants of doors and windows. The building measures 10.3m from east to west and 5.25m from north to south. The west walls are 0.5m wide and the north wall is 1.5m wide. The tallest remaining wall is 3.7m high. The north wall is the most intact, with over half of it still standing. Some timber joists and lintels have stayed intact. In the centre of the north wall is a large rectangular opening with a concrete lintel that was created in the 20th century, which was likely to have been used as the garage entrance, and there is a further rectangular opening to the right.
