King House was vacated by the Irish Army in 1969.
In 1987, after laying dormant for nearly 20 years, King House was acquired by Roscommon County Council. The house was in a state of dereliction and in 1989 an extensive four-year restoration plan began to restore the original structure and architectural integrity of the building.
Skilled artisans and local craftsmen used traditional techniques and materials to restore the three storeys and basement to their former Georgian glory.
An engaging exhibition tells the restoration journey of the house and a glass walkway installed in the attic gives visitors a unique perspective of how the house was constructed.
