Dublin Castle

Dublin Castle (Irish: Caisleán Bhaile tha Cliath) is a former Motte-and-bailey castle that is now a government complex and convention center in Ireland. It was chosen because of its location at the highest point in Dublin. It was the seat of the British government's administration in Ireland until 1922. The majority of the existing structures originate from the 18th century, albeit a castle has been on the site since King John, the first Lord of Ireland. The Castle served as the seat of English, and subsequently British, administration in Ireland under the Lordship of Ireland (1171-1541), the Kingdom of Ireland (1541-1800), and the United Kingdom of Great Britain and Ireland (from 1801 to 1900).

The complex was ceremonially handed over to the newly formed Provisional Government led by Michael Collins following the signing of the Anglo-Irish Treaty in December 1921. It presently accommodates each President of Ireland's inauguration as well as many State functions. The black lake ("Dubh Linn") that gave Dublin its name inspired the construction of the fortress. This pool is located on the lower channel of the River Poddle before it joins the River Liffey; when the castle was built, the Liffey was much bigger, and both rivers successfully guarded the castle. The Poddle now passes beneath the structure.

Today, the area itself is regularly used as an immersive teaching tool, informing both residents and visitors about the region's history and ongoing significance. This Dublin building, located just off Dame Street, initially opened in 1214, with succeeding builds frequently paralleling the need for repairs or a change in occupation.
