Built by the Society of Artists in 1765, the City Assembly House possesses the first purpose-built public exhibition room in Ireland or Britain. For twenty years after its opening, the works of Ireland’s greatest eighteenth century artists were shown here and it also served as an academy for the arts. For the first half of the nineteenth century it was used by Dublin Corporation as the City Hall, during which time it played an essential political role. Daniel O’Connell presided over meetings as Lord Mayor in the exhibition room and is reputed to have delivered the finest speech of his career there. It served as the Civic Museum for much of the twentieth century. Having been unused for some time, it is now under restoration by the Irish Georgian Society for use as their headquarters, lectures and exhibitions. An important survival of a rare and unusual type.
