The buildings along Old Street are not that old but some of them are several hundred years old. One of the buildings, just out of sight around the corner, has a date of 1744 on it. [See this post from last year.]
Old Street may not be the hub of the town's activity any more but is still fairly busy and the central section is pedestrianised, creating a more relaxing environment for shoppers.
See Bird's Eye View of this location. (The Google Street View car has not managed to cover this pedestrianised street!)
