I’m unsure of the exact date of this photo but would guess it’s 1920s or 1930s. Pictured is Calderwood Castle, from the Blantyre side of the Rotten Calder River. Just down from this on the right hand side is Blantyre’s Craigneith area up at the High Calder beyond Crossbasket.
Several old postcards of Calderwood Castle were incorrectly titled “Blantyre” when in fact the castle was in East Kilbride’s parish, the river here forming the boundary. The last part of the castle was demolished in 1951.
