Place & story
Plassey House
Plassey House combines an eighteenth-century country-house core with Victorian Italianate remodelling. Its front has a shallow central projection beneath a pediment, with an entrance portico carried on Corinthian-style columns. Decorated window surrounds and ornate interior cornices contribute to its character. The National Inventory of Architectural Heritage identifies it as a focal building beside the Shannon within the University of Limerick campus. Its architectural layers survive within a setting that has acquired a very different purpose. [2]
The opening of the institute
The University of Limerick’s archive records Plassey’s selection for the new National Institute of Higher Education because it offered proximity to the city and room for expansion. A planning board was established in February 1970 under Ed Walsh. After delays, the first 114 students attended classes on 26 September 1972, with the official opening the following day. Early campus photographs preserve the transition from demesne grounds to a developing educational institution. [3]
University status
The institute’s first graduation took place on 18 July 1977, with degrees awarded by NUI chancellor T. K. Whitaker. University status followed in 1989: Education Minister Mary O’Rourke announced the change in January, legislation followed, and the university was inaugurated on 14 September. The archive also records Thomond College of Education’s formal merger with the university in June 1991. These changes helped establish Castletroy’s enduring role in higher education. [3]
The older Castletroy houses
University of Galway research identifies Castle Troy as a nineteenth-century home of the Mattersons, proprietors of a bacon factory, and later of Colonel Richard Arthur Milton Henn. It also notes a cartographic complication: the first Ordnance Survey map labels this property Castletroy House, while the later twenty-five-inch map applies that name to another house farther south. The records therefore preserve two house sites whose similar names need to be distinguished. [4]
