One of the quadrants linking the main block to its pavilions at Strokestown Park, County Roscommon. This part of the building dates from the 1730s when Thomas Mahon commissioned architect Richard Castle to enlarge and modify an earlier house on the site. Castle undertook the project with exceptional skill by deploying a handful of familiar motifs, in this instance a pedimented doorframe below a recessed niche, both flanked by regular windows and oculi on their respective floors. The crispness of the cut limestone contrasting with the rendered surface of the walls enhances the overall impression of refined simplicity.
