Area characterisation: 

Barcelona is one of the most densely populated European cities with about 1.62 million people living in an area of just over 100 km2. The particularly favourable geographical location allows for a variety of natural phenomena to converge: two river mouths with a river delta each; the coastline, with sandy beaches and Montjuïc hill; the reliefs of the plain; and Collserola, a mountain range with an ancient landscape of highly modified forests.
