The brick building on the right here is the now defunct St. Mildred's Tannery. Until very recently, this was perhaps the last real industrial operation inside the city walls. It was not liked by the local residents because of its propensity to regularly generate the foul smell of rotting eggs. The Tannery has now moved its centre of operations to an industrial estate in Thanet.
The site is rapidly becoming a housing estate, with the internal buildings being demolished. The building on the left is recent, and is part of the development.
Why is it called St. Mildred's Tannery? Well, it takes its name from St. Mildred's Church which you will reach if you keep going straight on this road.
