The Kirna, known locally as Kirna House (previously also as Grangehill), is a Category A listed villa in Walkerburn, Peeblesshire, Scotland. It is one of three villas in Walkerburn designed by Frederick Thomas Pilkington between 1866 and 1869 for the Ballantyne family after Henry Ballantyne first bought land at that location to build a tweed mill in 1846. It is listed as a fine example of a Pilkington mansion retaining original external features, a fine interior, and for its importance as a Ballantyne property.
