Rock Hill House, dating back to the 17th century with a complete re-model and extension in 1832, the house and estate were taken into the hands of the State in the 1930s and used by the army until 2009, lay derelict for a while and then sold by the government and opened as a posh hotel by the new owners in about 2019 after much refurbishment.
I must try and have a walk around the very impressive looking gardens some time if a non-resident is allowed such a liberty.
