Calderwood Castle was a castle in East Kilbride. The castle was situated near the banks of the Rotten Calder Water.^[2][3] in what is now Calderglen Country Park.^[3] Most likely constructed in the late fourteenth to early fifteenth century by the Maxwell family, the original peel tower collapsed in 1773 after several days of severe weather.^[1][4] An earlier building is suggested to have stood on the site which belonged to the Barony of Mearns (Roland De Mernis), which passed with its lands to the Maxwells through marriage.^[5][6] The first known 'castle' was built on the site in the early 15th century as ascertained from stylistic designs known from images, as well as historical literature.^[7] Later in the mid 18th century and then 1840's a sprawling mansion house was constructed and extended on the site, with the latter development being executed in a spectacular form of Gothic Revival design, quite unique, and whilst the architect is not known, has been attributed to David Rhind, who was prominent during the period and on personal terms with the Maxwells of Calderwood. This architect is also thought to have designed the Maxwellton Schoolhouse, with the former beinga small weaving village which was situated on the old Calderwood Estate and still in good preservation as a conservation residential area within the new town of East Kilbride.,^[8][9] but it eventually fell into disrepair by the 1940s, with the final vestiges of the castle being demolished with explosives in 1951.^[2] Nothing now remains except ruins and rubble.^[1] The now-ruined Craigneith Castle is nearby.^[1][2][10]
