Pottergate Arch, Lincoln. In 1285, to protect it's properties, the Lincoln Cathedral community built a high wall to enclose them. There were many gates of which three (plus a posterngate) still exist today. Pottergate Arch, as it is now known, was the south-east gateway to the Cathedral Close and is seen with the Cathedral in the background. Flanked by properties either side it was in use as the main way into the close from New Road (now Lindum Road) until 1884 when a road was constructed round the Arch on the western side and restoration work on the Arch was carried out. For the next 54 years up traffic passed round the arch and down traffic through it but with the advent of double decker buses in Lincoln that situation had to change and in 1938 a road was constructed on the eastern side & the Arch was made into an island with traffic passing either side.
