 The Order was without a ceremonial home until 1881 when arrangements were made to display banners , helms and hatchment plates ( the equivalent of stall plates , in the absence of stalls ) in the Great Hall , officially called St. Patrick 's Hall , in Dublin Castle . On the establishment of the Irish Free State the banners of the living knights were removed . When the Hall was redecorated in 1962 it was decided that it should be hung with the banners of the members of the Order in 1922 . The existing banners were repaired or new ones made ; it is these banners which can be seen today . The Hall , which was renamed St Patrick 's Hall from its association with the Order , also served as the Chancery of the Order . Installation ceremonies , and later investitures , were held here , often on St Patrick 's Day , until they were discontinued . A banquet for the Knights was often held in the Hall on the occasion of an installation . St Patrick 's Hall now serves as the location for the inauguration of the President of Ireland .
