[citation needed] Located on the Bay of Cascais along the shore of the Citadel of Cascais, the marina plays host to numerous high profile sailing events, such as the America's Cup World Series, the World Match Racing Tour, and the Audi MedCup.

In 2018, the city announced the marina will be redeveloped, featuring a €60 million green roofs scheme, that when complete would be a mixed-use luxury and environmentally conscious destination.

The concession for the construction and operation of the marina was awarded for 75 years to a private company, by contract with the Portuguese State, on September 21, 1995.

[4] Proponents of the marina argue that it has not affected the visual appeal of Cascais, that all the surrounding historical and architectural heritage was preserved and carefully integrated, and that it has led to further regeneration of the area, particularly in the citadel.

[5] Cascais Marina has 650 mooring stations able to receive vessels up to 36 meters in length.
