TAKING a tour of Darlington town centre more than a century ago, WJ Mountford walked off High Row and up Clark’s Yard. “The old houses and workshops that crowded this picturesque and narrow way have nearly all become warehouses,” he wrote in his unpublished memoires in 1908. Then he, like Memories 510, looked up. “There is an interesting old leaden spout at the south side of the yard which bears the initials ‘IP 1767’,” he noted, referring to the drainheader on the top of John Pease’s old house. And then he looked down, and said: “A wooden gate bearing iron spikes stops the way to a dozen stone steps leading to some dark, damp, ancient chambers beneath.”
