What is "killiechassie"

Killiechassie is a country estate and house near Weem, about a mile northeast of Aberfeldy, in Perth and Kinross, Scotland. The estate lies on the banks of the River Tay in some 12 acres, about north of Edinburgh. It was owned by the Douglas family in the latter part of the 19th century, and a new house was erected in 1865. A dovecote by the house was listed as Grade B on 9 June 1981. The house was purchased by author J. K. Rowling in 2001.
