 The castle's former composer-in-residence, John Maxwell Geddes, wrote a "Postlude for Strings" in protest at plans to sell the castle.The Council placed the building on the market in 2010, and in response the South Cowal Community Development Company (SCCDC) was formed to explore community ownership of the castle, though their initial bid was rejected by the Scottish Ministers in 2011.An agreement was reached with a holiday company, which then pulled out of the sale in 2013 forcing the Council to market the property once more.
