Dublin Castle

Dublin Castle is a major Irish government complex, conference centre, and tourist attraction. It is located off Dame Street in Dublin. From 1204 until 1922, it was the seat of English, and later British, rule in Ireland. During that time, it served principally as a residence for the British monarch’s Irish representative, the Viceroy of Ireland, and as a ceremonial and administrative centre.

After the signing of the Anglo-Irish Treaty in December 1921, the complex was ceremonially handed over to the newly formed Provisional Government led by Michael Collins. It now hosts the inauguration of each President of Ireland and various State receptions.

It is a historic site, dating from 1204, with 2 museums, cafes, gardens, a library, and staterooms filled with a fascinating history.
