The United Kingdom (UK) consists of England, Scotland, Wales and Northern Ireland, each of them with distinguished geographies. England is the home of London, a global financial and cultural centre and river Thames, major landmark in the UK. Scotland is a land of Highland mountains, offshore islands of Skye and Lewis, and the legendary Loch Ness monster. Wales is mountainous, but also has miles of beaches and castles at Cardiff, Caernarfon, Caerphilly and Conwy. Northern Ireland is known for its scenic Glens of Antrim and a coastline featuring the Giant’s Causeway, amazing natural formation of hexagonal rock columns.
