Belfast City Hall is another government building that should be visited. Located in the city center, this handsome structure was built in 1906 and remains one of the most distinctive landmarks in Belfast's downtown core. Tourists are welcome to explore the building as part of a guided tour, so popular that they've become one of the top free things to do in Belfast (tours are available on a first-come, first-served basis, so allow plenty of time in your schedule). Highlights of these one-hour tours include seeing a good-sized art display and historic stained-glass windows and an exhibit outlining the city's history. Afterwards, you can browse the gift shop or visit the café.
