Topography

Milan is located in the north-western section of the Po Valley, approximately halfway between the river Po to the south and the foothills of the Alps with the great lakes (Lake Como, Lake Maggiore and Lake Lugano) to the north, the Ticino river to the west and the Adda to the east. The city's land is flat, the highest point being at 122 m (400.26 ft) above sea level.

The administrative comune covers an area of about 181 square kilometres (70 sq mi), with a population, in 2013, of 1,324,169 and a population density of 7,315 inhabitants per square kilometre (18,950/sq mi). The Metropolitan City of Milan covers 1,575 square kilometres (608 sq mi) and in 2015 had a population estimated at 3,196,825, with a resulting density of 2,029 inhabitants per square kilometre (5,260/sq mi). A larger urban area, comprising parts of the provinces of Milan, Monza e Brianza, Como, Lecco and Varese is 1,891 square kilometres (730 sq mi) wide and has a population of 5.27 million with a density of 2,783 inhabitants per square kilometre (7,210/sq mi).

The concentric layout of the city centre reflects the Navigli, an ancient system of navigable and interconnected canals, now mostly covered. The suburbs of the city have expanded mainly to the north, swallowing up many comuni along the roads towards Varese, Como, Lecco and Bergamo. In the 21st century the Navigli region of Milan is a highly active area with a large number of residential units, bars and restaurants. It is also a well-known centre for artists.
