College Green, Dublin 2
Currently home to the Bank of Ireland, this imposing structure was built in 1729 to house the Irish Parliament, which it did until the passing in 1801 of the Act of Union. It still retains many stunning architectural features dating from its heyday. Highlights include the windowless front portico, built to avoid distractions from the outside when Parliament was in session, 18th-century tapestries, golden mace, and a sparkling crystal chandelier. There is arguably no other venue in the city with a greater sense of occasion.
