ruins of 'Corsehill House' were removed about the beginning of the 19th century and only foundations could be traced when he wrote. He also thought that "Reuincraig" (i.e. Ruin Craig) was not an original name. If Dobie is correct, the ruins published as "Corsehill Castle" on the OS 6", must be those of "Reuincraig", both because they are standing remains, and because they are on the west bank of the burn. MacGibbon and Ross, describe Corsehill Castle at the end of the 19th century as a very ruinous mansion of a late date and apparently of an 'L-plan', belonging to the period 1542–1700 so they must be referring to Corsehill House. Grose, in 1797, published an illustration of 'Corshill House', but does not give its exact location. He mentions that "at a small distance from this ruin are some small remains of a more ancient building belonging to the same family", he is therefore referring to 'Old Corsehill Castle'.MacGibbon, Page 495. General Roy's Military Survey of Scotland (1745–55) marks 'Ravenscraig' as 'Old Corsehill' and also marks the 'new' Corsehill on the other side of the burn, thereby apparently confirming that they both had the same name and one replaced the other, although only 'Old Corsehill' is still in any way visible, just some foundations of 'new' Corsehill being apparent in 2007, the rest of Corsehill House being removed in the 19th century. Traces survive of a much silted up ditch that may be the remains of a track which led from the Stewarton to Dunlop road to the castle and then on to the cattle creep that runs under the railway line giving access to the east side where Corsehill House once stood. The fine old sandstone bridge which carried the road up to Corsehill was demolished in the early 1990s. A local tradition was that the iron 'jougs' on it were for imprisoning witches, although it may be that these were linked to the Barony Court functions of the old Corsehill Barony, the records of which still survive and make reference to the stocks.Brown, George (2006). Oral communication to Griffith, Roger S.Ll. Adamson on his walking tour in 1875 records that Old Corsehill Castle was never very large and that the surviving portion showed signs of recent repair. A great treasure is said to lie buried beneath the founds in a dark chamber and that a local man had
