Large, square, brick structure 2.43m wide constructed of a double skin of mid orangey-red bricks bonded with hard
mortar, the dimensions and form of which suggest a date of the mid 18th to early 19th century. The
height of the structure was not ascertained. It was filled by a deposit of highly-compacted pale
yellow gravel slightly darkened with soot around the edges. Infrequent inclusions of brick fragments
are present. The location of this structure along with its form indicates that it may be the chimney
shown on the 1919/1967 Ordnance Survey maps. Abutting the exterior of this structure is a
layer of redeposited natural clay and mudstone mixed with demolition debris which was probably used
as a backfilling material for the voids around the chimney structure during the landscaping process. (1)
This chimney structure is likely to be the remains of the chimney shown on the 1919 and 1967
historical ordnance survey mapping, and was likely used in both the House of Correction and Lacy Factory (1)
