Serra da Estrela (European Portuguese pronunciation: [ˈsɛʁɐ ðɐ (i)ʃˈtɾelɐ]) is the highest mountain range in Continental Portugal.

It includes mainland Portugal's highest point at 1,993 metres (6,539 feet) above mean sea level (although the summit of Mount Pico in the Portuguese Azores islands is higher).

[2] The mountain range, situated between the municipalities of Seia, Manteigas, Gouveia, Guarda and Covilhã, is about 100 kilometres (60 miles) long and is 30 km (19 mi) across at its widest point.

The Covão dos Conchos looks like a natural sinkhole within the lake at first glance, but it was constructed as a spillway in 1955 and acts as a water diversion from Ribeira das Naves to Lagoa Comprida.

A legend associated with the mountain is mentioned in chapter 41 of the American literary classic, Moby-Dick: Archaeological investigations have allowed a picture of life during the fifth millennium BC, the Early Neolithic to emerge, where small communities sustained themselves by small game hunting, the gathering of acorn and other winter fruits, and migratory pastoralism.

The significance of the Serra da Estrela in Neolithic culture can be seen in the discovery that megaliths in the Mondego River basin were predominantly built with an alignment that allowed the mountain range to be seen from within the inner chamber.
