Two mid 19th century lime kilns off Wragby Road, set within a former limestone quarry (see MLI90638). Documentary sources of the mid-19th century name the site as Nelthorpe's Quarry, being owned by a William Tweed Nelthorpe, lime burner. The lime-burning activity on this site was relatively short-lived, however, with both the quarry and lime kilns becoming disused by 1877. In the 1890s, a house called The Dell was built on the eastern edge of the quarry (see MLI126057), the lime kilns were infilled and the bank within which they stood landscaped as part of the associated garden. The lime kilns were partly exposed at the end of the 20th century but still remain largely buried. The kilns are of the draw kiln type, and are arranged in an approximately north to south aligned block, built into the bank which marks the western edge of the quarry. A narrow passageway flanked by walls of roughly dressed limestone leads from the floor of the former quarry to a tall brick-arched opening, about 1.4m wide, set into the side of the bank. This archway opens into the central lobby, 1.6m in width, which gave access to both kilns. The rear wall of the lobby is constructed of limestone and tapers upwards to a brick-vaulted roof. In the south wall, which is constructed of brick, a smaller arched opening of about 0.75 high and 0.5m wide represents a draw-hole through which the southern kiln was lit, and ash and lime subsequently removed. In the north wall, which is constructed of limestone and brick, a larger opening about 1.2m wide and 2m high provided access to a draw hole in the northern kiln. The firing chambers (pots) of the kilns, now infilled, are believed to be about 5m in diameter and thought to survive to a height of at least 6m, buried within the bank. Roughly dressed limestone blocks on the side and top of the bank indicate the location of the buried pots. The pots would have been filled from the top of the bank through open tops, in alternating layers of fuel and limestone, providing a continuous feed lasting up to a few weeks for each firing. This double-kiln block represents a rare survival of a pair of draw kilns in an urban context. {1} Although not labelled, the quarry is depicted as extant and including 'lime kilns' on Dewhirst and Nichols 1839 map of Lincoln, indicating operation of the site was in progress by at least this date. The site is named as Nelthorpe's Quarry on Padley's maps of 1842, 1851 and 1868, although later maps (produced from 1883 and onwards) show the site to have ceased production. {2}
