Sale of the castle
In 2019, the building and 70-acre grounds of Brechin Castle were put up for sale, with James Ramsay, 17th Earl of Dalhousie and chief of Clan Ramsay citing prohibitive upkeep costs as the motivating factor. A news report stated that the castle has eight reception rooms, 16 bedrooms and 10 bathrooms. Another news report made this statement: "Of the early medieval building little evidence remains. The oldest part of the current castle is the kitchen block, where can be seen a stone bearing the date 1703, but in 1711 major renovations were made which gave the building its current form". Edzell and Invermark and the family businesses – including Brechin Castle Garden Centre and Peggy Scott’s – were not being sold.
