London is the largest city in the EU with about 14 million inhabitants and one of the most important commercial centers and financial centers in the world. Many sights, a lively nightlife and large shopping centers make the city on the Thames an attraction for tourists from all over the world. Every year about 18 million people visit the city, making it the most visited city of Europe. London is not immune to flooding and high tides, however, as the tides of the North Sea are noticeable and the city built levees and barriers to protect the city from storm surges. Southeast England is climatically a favored area, compared to other parts of the UK, and because of its proximity to the mainland, London has always been the gateway for conquerors and explorers.
