Lake Como , also known as Lario, is a lake of glacial origin in Lombardy, Italy. It has an area of 146 km2 (56 sq mi), making it the third-largest lake in Italy, after Lake Garda and Lake Maggiore. At over 400 metres (1,300 ft) deep, it is one of the deepest lakes in Europe. Its characteristic "Y" shape resulted from the movement of the ancient Adda glacier, which was diverted by the mountainous terrain and carved the three branches.

Located at the foot of the Alps , Lake Como has been a popular retreat for aristocracy and the wealthy since Roman times, and a major tourist attraction with many artistic and cultural gems. The homonymous city was named Novum Comum by consul Julius Caesar in 59 BC. Its shores are dotted with numerous villas and palaces, such as Villa Olmo, Villa Serbelloni, and Villa Carlotta, known for their historic architecture and elaborate gardens.
