The citadel stands over the marina
Cascais’ 600-berth marina is located behind the citadel and is where Lisbon’s most affluent population keeps its deck boats and sleek yachts.
It’s faced by a few restaurants and bars, which serve those who moor their boats, locals and tourists.

The marina a pleasant place for a stroll, heading in a western direction towards the Santa Marta Lighthouse. The lighthouse and its neighboring building (Casa de Santa Maria) may be visited, but the main attraction is the calm, crystal-clear water of the beach of Santa Marta by the palatial residence of the counts Castro Guimarães. You may also see the interior of that building, which is now a museum, or continue your walk down the road, all the way to the rock formations of Boca do Inferno.
