roughly in line with the rear wall of the calcining kilns centred 100m to the north. This has been interpreted as the remains of a second bank of calcining kilns which, according to an 1865 poem, was badly designed and collapsed. The monument also includes the surviving tips of calcine dust that lie to the east of the calcining kilns.
