The property is situated in Quinta da Marinha, one of the most exclusive areas of Cascais, renowned for the high property values of the homes built there.

The property in question covers 2,000 square metres, equating to a price of €20,000 per square metre. The property information shows that the house has unobstructed sea views. It also includes a tennis court, an internal lift, and décor described by idealista as “fantastic.”

The purchase of this property shows how the luxury property market is growing in Portugal and how the Portuguese real estate market is attracting foreign buyers, particularly in the area of Cascais, known as one of the most expensive in Portugal.

Most expensive houses in Portugal

According to Sic Notícias, in 2024, a house in Estoril was sold for €32 million, and at about that time, there were rumours that Cristiano Ronaldo had visited it.

At the beginning of 2026, idealista also reported that Cristiano Ronaldo's house had been sold for €35 million.

Currently, the record for the most expensive house is reportedly €40 million, as mentioned above. Nevertheless, Forbes Portugal reported in 2024 that a house going on sale in 2026 would cost €45 million. In the Algarve, there is still no information about the house's price or whether it is already built and ready for sale.
