Rev. Robert Nicholl Carne was a Welsh rector, landowner, and a magistrate and Deputy Lieutenant of Glamorgan. He built Dimland Castle at the end of the 18th century upon land left him by his father, from whom he inherited 99 acres.

Dimlands was a small scale, gentry house on the north side of St Donats Road about 6 miles (9.7 km) southwest of Cowbridge in the Vale of Glamorgan, southeast Wales. Built like a small Tudor castle, it is situated about 1 kilometre (0.62 mi) back from the clifftops of the Bristol Channel between Llantwit Major and St Donats. The main house was demolished after a fire in 1948, but its lodge, in a similar castellated style, survives and became a Grade II listed building on 9 October 1982.
