48. Dunluce Castle, Ireland
The Dunluce Castle in Ireland is one of the most beautiful sights in Ireland. It is a ruined medieval castle located in the northern part of the country and sits right at the edge of basalt outcropping in the town of Antrim in between Portballintrae and Portrush. The castle looks even more magnificent for it is surrounded with extremely steep drops on both sides. The site can be accessed by taking the Belfast-Derry railway line which is operated by the Northern Ireland Railways.
