A medieval/post medieval chalk pit and limekilns were formerly located at Mount Pleasant. The pit and one limekiln are marked on the Ordnance Survey 1st edition map of c.1871 - 1872. On the 2nd edition map (c. 1896 - 1898) there are two limekilns marked, whilst on the third edition (c. 1906) these are marked as "Old Limekilns". The chalk pit is disused by the 4th edition map (c.1931 - 1940).

Boundary marked but not named on OS 6" 1st ed (1872). Marked and named 'Chalk Pit' on 2nd ed (1898), and marked, but again unnamed on 3rd ed (1908). Boundary still present on modern maps. Pair of lime kilns marked on 2nd ed map (1)

A desk-based assessment of a nearby site suggests that the pit may have dated from the medieval period as it may be a feature visible on a 1400 AD map of Thanet recorded as "Puteus Thunor" or "Thunor's Pit". (2)

A chalk pit of post-Medieval date was visible as an earthwork in RAF/106G/UK/1378 V 5080 04-APR-1946. It was recorded as an earthwork on Next Perspectives APGB Imagery 07-APR-2021. This feature was mapped as part of the Historic England Isle of Thanet project in 2024. (3-4)
