In August 1957 Mr H. C. Calver found that workmen engaged on the site of the Co-operative Society's butcher's shop (no 15 Long Wyre Street) had sunk a shaft in which a circular Roman feature was found. The circular construction was made of Roman tiles, 11" below the surface, and 4ft 9" in overall diameter, the wall being one foot thick. The interior face of the wall was lined with three inches of clay. The floor consisted of two layers of Roman tiles. This chamber was crossed by a lead pipe, placed about 4" above the floor and passing through the wall at each side. It was 3" diameter at one end, tapering to 2.5" at the other end, being 14ft long over all, though the south end continued under the next property. In the middle of the chamber, on the upper side of this pipe, were the remains of a return pipe coming upwards. The main pipe (and presumably the upright one) was of oval section, with a lapped joint one inch wide. At the north end (the smaller) the pipe projected a little less than a foot from the wall of the round chamber and then turned downwards at a right angle. The angle was protected by a rounded bulb of lead. The vertical pipe was only nine inches long and entered the flat lead top of a lead cistern which was 2ft square. The lead walls were 7/8" thick, as was the flat bottom. There was not more than half an inch of earth on the flat bottom, which was about 5ft deep from the top. The flat top was 1/4" thick. <1>
