The name Blackaddie has been derived from words meaning black water. The River Nith which runs alongside Blackaddie is the most likely origin for such a name. The house itself was originally built as a rectory to St. Brides church and dates back as far as the beginning of the 16th century, reputedly built for the Crichton Family and the Admiral Crichton lived here. Over the years a number of extensions have been added to the original house and Blackaddie has evolved becoming the charming building you see today. Set in two acres of pretty gardens the Country House Hotel enjoys magnificent views of the River Nith and the breath-taking Lowther and Queensbury Hills beyond.

With its important position on the banks of the Nith and situated at a major crossroads, by the 18th Century, Sanquhar had become an important inland market for the then wool trade. The house also has connections to Robbie Burns as one of his best friends once owned the house meaning he must have visited on numerous occasions.
