As you follow Bailgate you are walking along the Roman Colonnade with the Forum to your left.
If you look on the ground along the road you will see circular stone setts. These show the position of a row of 19 columns stretching 84 metres that made up the front and main entrance to the Roman forum, forming a portico. Most were discovered by workmen in 1878 along with a sewer beneath the main Roman street.
Some of the column bases are still visible in the cellars of the shops and private houses along Bailgate (these are not open to the public). There is a stone plaque on the wall of one of the houses showing the location and date of the discovery.
