There is no archaeological evidence for The Side pre-dating the Norman Castle, but it is an obvious pathway to the bridging point across the Tyne. The Side connected what may have been the earliest harbour and the bridging point to the principal market street. Connected Sandhill with Bigg Market and through to Newgate Street. In The Side there were shops for merchants, drapers and other trades. Bourne describes the street as a very great descent, narrow in width, from the Head of it to Castle Stairs, where it opens out in a spacious breadth into Sandhill. It had shops of merchants, goldsmith's, milliners, upholsters etc on either side. The east side of the street from the upper part to Allhallow Pant (HER 6529) was called Cordiner or Cordwainer Rawe. Gray reports that in the middle of The Side (presumably near Dog Leap Stairs) is an ancient stone house, an appendix to the Castle, which belonged to the Lord Lumleys (see HER 6591). According to Bourne, the tenements in The Side supported the chantries of St Catherine, SS Peter and Paul, St Cuthbert, in the church of St Nicholas. Welford describes a house once belonging to the nuns of St Bartholomew on the west side of The Side. Le Side (1366, 1425), the Syde (1378, 1401), la Side (1393), the Side (1430), the Syd (1587) and The Sydde (1596). Means a broad walk. Name derives from the fact that it was the route by the side of the Castle. Originally named in three parts; Foot, Middle and Head of Side. The Head of Side was formerly very narrow with tall timber-framed buildings with upper storeys nearly touching. Occupied by dealers in cheese, bacon and butter as these perishable products were kept cool in shade produced by tall buildings. Fire in 1900 destroyed what was left of the medieval buildings. The Middle of Side was the broadest part of the street before Dean Street was created. Goldsmiths, milliners, upholsterers and similar trades were prominent here. Foot of Side was originally only right hand side going towards Sandhill. The opposite (eastern) side of the lower part of The Side was known as Flesher Rawe (le Flesherwer Rowe (1377-78), Flesherawe (1425), Flesshewerrawe (1437), Flescher raw (1499), Flesher Rawe (1578), Fleshwerrgate (1361), la Fleswergate (1393)) - probably named after butcher's shops. There was a messuage in The Side in 1430 called Lyleplace, and another called Wodmansland in 1425. Dated C13-15th.
