Northern Ireland's capital city, Belfast emerged as a settlement during the Bronze Age, built at the mouth of the River Lagan. The port town became a considerable city during the 18th century when it expanded through industry, becoming the country's largest city. Today it is now home to an abundance of restaurants, bars, shops and a vibrant theatre scene. Rent a car from George Best Belfast Airport and you can take in the city's historic landmarks. Visit the Romanesque St Anne's Cathedral, take a trip to Belfast Castle Estate, which overlooks the city, and don't forget the Belfast City Hall with its green copper domes offset by the pale Portland Stone and of course the Titanic Belfast experience.
