Lost medieval Dublin castle found hiding inside university building

A medieval castle believed to have disappeared around 150 years ago has turned out to be hiding in plain sight inside a university building in Dublin, with researchers finding that its ancient walls and courtyard survived beneath the later structure.The discovery concerns Roebuck Castle on the Belfield campus of University College Dublin (UCD). The Norman castle was long thought to have been cleared away when the present Roebuck Castle was developed during the 19th century. New research by UCD medieval architectural historian Professor Tadhg O’Keeffe has now shown that substantial parts of the medieval structure remain intact within the building.A castle hidden behind a Victorian facadeFrom the outside, the building appears to be a much later Victorian structure. But O’Keeffe’s research, published in Archaeology Ireland, found that the medieval castle was not completely demolished as previously assumed.
