Oast complex at Congelow Farm, Benover Road, Yalding. The 1st Edition O/S map shows two separate buildings, one with 2 roundels and the other with 4 roundels. The 2nd and 3rd Edition O/S maps show that an additional roundel has been added to the existing 2 roundels and the 4 roundels have remained unchanged. The 4th Edition O/S map indicates that only 2 of the 3 roundels remain and the building inbetween has been demolished. Also 2 of the 4 roundels would appear to have been demolished. The current O/S map shows only a single oast remains.
