I have never liked this building but I am certain that if it is demolished it will be replaced by something even worse.

Liberty Hall is the headquarters of the Services, Industrial, Professional, and Technical Union (SIPTU). Designed by Desmond Rea O'Kelly, it was completed in 1965. It was for a time the tallest building in the country, at 59.4 metres, (195 feet) high until it was superseded by the County Hall in Cork city, which was itself superseded by The Elysian in Cork.

Liberty Hall is now the fourth tallest building in Dublin, after Capital Dock, Montevetro (now Google Docks) and the Millennium Tower in Grand Canal Dock.

Liberty Hall is more historically significant in its earlier form, as the headquarters of the Irish Transport and General Workers Union early in the 20th century, and also as the headquarters of the Irish Citizen Army (ICA).

On 19 October 2006 it was announced that SIPTU (into which the Irish Transport and General Workers Union had merged in 1990) was seeking planning permission to demolish Liberty Hall and build a new headquarters on the same site. By October 2007 SIPTU had selected a shortlist of architects to design the new building and was planning to demolish the current building in 2009. In January 2008 the Dublin architects Gilroy MacMahon, who had designed the new stands at Croke Park, were chosen to design the new Liberty Hall. In February 2012 SIPTU was granted planning permission by Dublin City Council to demolish the present structure and build a 22-storey replacement, with a height of about 100 metres. The new building would have included office space, a theatre and a "heritage centre". However, in November 2012 the planning permission was overturned by An Bord Pleanála, which ruled unanimously that the new building would be "unacceptably dominant in the city".
