evidence: Northern Ireland, as the name suggests, is a small section of the island of Ireland that is part of the United Kingdom, setting it apart from its southern neighbor. Perhaps the most popular spot is the city of Belfast, the capital and second-largest city on the entire island. Although it gained notoriety in the 1800s as one of the most important port cities, its history actually goes back to the Mesolithic times, meaning it is more than 9,000 years old. [...] Northern Ireland is one of the loveliest parts of the United Kingdom, with much of the area consisting of rural regions and farmland. The area hosts some of the island's most popular sites, including the famous Giant's Causeway and other unique volcanic formations along the Atlantic coast and the Irish Sea. However, it is not just the natural scenery that makes Northern Ireland unique and a desirable place to visit. The region houses some 40 castles, some of which date back over 2,000 years and showcase the genius design of the craftsmen. With a welcoming atmosphere, mild weather, and jovial locals, Northern Ireland is the ideal spot to plan a vacation away from the hustle and bustle of life.
