This 18th century neoclassical palace was built for the then Dutch Consul. It later came into the hands of the 5th Marquis of Marialva who extended it significantly, adding the arch in 1802.
The Seteais Palace occupies a prime position on the edge of the Serra de Sintra overlooking the countryside and town. It is surounded by extensive gardens with many fruit trees and features inspired by the then popular Romantic movement.
In 1946 the Palacio de Seteais was acquired by the Portuguese government becoming a hotel in 1954. It is now the five star Tivoli-Palacio de Seteais Hotel. Still open as a tourist attraction, the palace is listed by UNESCO as part of the Sintra World Heritage site.
