Cascais is a coastal municipality in the Lisbon region of Portugal, situated along the Atlantic coastline. This seaside city sits on the edge of the Estoril coast, and its local aviation needs are served by the Cascais Municipal Aerodrome. The economy and local identity of the municipality are built on its standing as a premier coastal destination within the Lisbon metropolitan area.
Cascais is an exceptionally expensive place to buy property compared to the rest of Portugal, with average prices nearly four times the national average. The housing market concentrates heavily in Cascais e Estoril, which holds far more of the housing stock than any other district and stands out as a highly expensive area. Carcavelos e Parede and Alcabideche also contain significant portions of the local housing, though their prices are much lower than those in the central coastal hub. For those seeking the most exclusive real estate, the small district of Fontaínhas has by far the highest prices in the municipality, costing nearly three times as much as the city average.
