Dublin Castle (in Irish: Caisleán Bhaile Átha Cliath) is just off the famous Dame Street in the centre of Dublin, Ireland. This beautiful building was formerly the fortified seat of British rule in Ireland until 1922, and today serves as a major Irish governmental complex. Most of the complex dates from the 18th century, though a castle has stood on this same site since the days of King John, the first Lord of Ireland (XII century). Upon establishment of the Irish Free State in 1922, the complex was ceremonially handed over to the newly formed Provisional Government led by Michael Collins. It is a large and interesting compound for tourists today, with many historical aspects worth visiting.
