Limekilns at Bohetherick at Sx422679

The limekilns at Bohetherick, likely built in the late 18th century, are depicted in a watercolour from 1817. Constructed from slatestone rubble with stone dressings, the kilns feature a triple kiln design with a central rectangular kiln flanked by smaller kilns on each side. They are built into the bank for top loading and are situated on the bank of the River Tamar for easy water access.

The central kiln measures approximately 7 metres in length and 5 metres in depth. Its front features a central pilaster that rises to a string course, with the flanking wings set back. The right wing includes a half-arch that leads to an internal vault, which has a round arch at the rear left and a stoke hole for the central kiln. There is also a stoke hole on the right side for the end kiln. The front of the right wing has a blind pointed arched window with deep reveals.

The left wing features a 4-centred arch with a roughly hewn keystone, similar to the internal vault that includes a stoke hole for the central kiln, as well as additional stoke holes at the rear and left. The left side of the kiln has another round arch with a vault and an upper blind window with a pointed arch. At the top, there are three circular openings for the kilns, surrounded by rubble walls. The architectural design of these kilns is notably unusual. The watercolour, signed MM and dated 1817, is part of the collection at the Royal Institution of Cornwall.
