AIB is to sell its bank premises at the junction of Lower O'Connell Street and Lower Abbey Street in Dublin 1, following a decision to merge the business with its other branch in O'Connell Street.
Agent Druker Fanning & Partners is quoting a guide price of over £2.5 million for the building which is to be sold by tender.
The landmark building has over 7,500 sq ft of space on five levels, including 2,200 sq ft in a superb double height banking hall with a glazed and ironwork dome, marble floors and pillars and glazed tiled walls.
The striking facade has been described as "a free form of classical renaissance".
There are two passenger lifts serving the upper floors and self contained access from Lower Abbey Street.
The building had an important link with the 1916 rising. It housed the Irish School of Wireless, where the rebels used the radio equipment to alert the world to the rising.
The building was damaged by British forces and eventually redeveloped in 1922 as a branch of the Munster and Leinster Bank.
It is one of the trophy buildings on the city's main street, which is now a priority area for upgrading by Dublin Corporation.
