Liberty Hall is an embodiment of the functional aesthetic of the International Style, with its simple slender form, transparency of structure, and sparse ornament. The copper cantilevered roof, however, is employed to reduce the visual impact of the core structure, adding some aesthetic interest while echoing that of Busáras nearby. A glazed curtain wall allows light to filter through the building, and provided a sense of transparency when viewed from outside, until the windows were shattered by a car bomb explosion in 1972 and subsequently replaced with reflective glass. The site has considerable historical relevance, having served as a soup kitchen during the 1913 lockout, and it was from here that the Irish Citizen Army marched to the GPO to take part in the Easter Rising, during which time the older union headquarters building was shelled and left badly damaged. The old building was retained until the 1960s, when the present building was constructed. Liberty Hall has been employed for cultural and artistic projects. Standing as one of the most prominent examples of International Modernism in the country, and constructed at a time when there was little precedent for this scale or type of structure in Ireland, Liberty Hall has become an icon of Dublin and makes a significant contribution to the architectural, historical and cultural heritage of the city.
