Prestigious Off-Market Property: Historic Mansion in Cascais Bay | Representative Headquarters & Private Residence
A landmark of power in Cascais Bay. Available for the first time in generations, this 1920 mansion, built on the ruins of the former Paço dos Marqueses, is not just a residence; it is a statement of status. With a gross area of 1357m² and designed by Raul Lino and Guilherme Gomes, it offers a monumental interior cloister, private chapel and a unique location on the seafront. Prepared for use as an embassy or corporate headquarters, it combines historical nobility with the functionality of 20 private rooms and complete service areas. Strictly confidential.
An Architectural Legacy on the Front Line
We present, under strict confidentiality, one of the most emblematic architectural landmarks on the Cascais Line. Built in 1920 and designed by masters Guilherme Gomes and Raul Lino, this mansion stands on the foundations of the former Palace of the Marquises of Cascais. More than just a property, it is a habitable work of art in the prestigious Bay.
Once through the gates, privacy is absolute. The entrance is through an impressive covered cloister, the beating heart of the house, where natural light falls on the stone arches, creating an unparalleled setting for official receptions or corporate events.
This ground floor, measuring 651m², is dedicated to grand entertaining: stately living rooms with fireplaces, a billiard room and a formal dining room connected to balconies overlooking the sea, offering uninterrupted views from the Marina to Estoril.
On the upper floors (1st and 2nd), the residence reveals its intimate side. With a combined area of over 700m², it offers a flexible configuration of 6 to 8 bedrooms. The 4 main suites stand out, including the Suite in the turret, which serves as a private lookout post over the Atlantic. The exclusivity is sealed by the existence of a private chapel, a rare detail that attests to the uniqueness of the property.
Designed to function with total autonomy, ideal for a diplomatic or family structure (Family Office):
Service area: Spacious kitchen with pantry, 2 pantries, machine room and dedicated rooms for resident staff on the ground floor.
Exterior: Plot of land with private swimming pool, changing rooms and protected gardens.
Parking: Internal capacity for 5 cars.
This is a ‘trophy’ for those who understand the value of history and permanence. Available for long-term rental, the property is currently undergoing renovation to ensure maximum comfort, with delivery scheduled for early 2026.
To schedule a private viewing, pre-qualification and signing of an NDA are required.
