Orchardton Castle is a Grade B listed Scottish Baronial stone castle built in the 1880s by William Douglas Robinson-Douglas in Auchencairn, Dumfries and Galloway, overlooking the Solway Firth. The castle contains over 40 rooms across four floors and sits on 5 acres of grounds featuring botanic gardens, woodland, a private pond, paddock, and stable block with direct access to a private beach. Currently operated as a family home with exceptional potential as a wedding venue or boutique hotel, it represents a striking example of 19th-century Scottish castle architecture in Southwest Scotland.
