Edmondstown House, otherwise known as Saint Nathy's, is a rare example of High Victorian Gothic in County Roscommon. The construction of such an architecturally expressive structure was an ambitious project for the original owner, Captain Arthur Costello. Edmondstown House exhibits many features typical of High Victorian architecture, famously employed by architect such as Deane and Woodward, and J.S. Mulvany. These architectural elements include the octagonal tower and the string courses of red brick framing the pointed-arch window openings, and the decorative cast-iron roof finials.
