The General Post Office was designed by Francis Johnston who was an architect with the Board of Works, in Greek Revival Style. The main section of the building was made with Wicklow granite and the portico of Portland stone.
It was the main stronghold of the Irish Volunteers in the 1916 Rising and nowadays the General Post Office offers a wide range of services.
The General Post Office (GPO) is remarkable not just for the special place it holds in Irish history and for its handsome architecture but for the fact that – after two centuries – it continues successfully to fulfil its original purpose as the headquarters of the Irish Post Office. A place of business and public service, of remembrance, protest and pageantry, the GPO deserves the unique place it holds in the affections of Irish people everywhere.
The GPO also houses The An Post Museum. The 'Letters, Lives & Liberty' exhibition, part of the Museum, explores the influence of the Post Office in Ireland and offers an insight into the role played by Post Office people in the development of Irish society over many years. From stamps and stamp collecting to An Post's copy of the 1916 Proclamation and the little known story of the staff who were actually in the GPO on Easter Monday, the exhibition is a unique way to learn about the importance of the Post Office in Irish life.
