The property has an extraordinary location in Sintra idealista

While the Castelo dos Mouros crowns one hill and the famed Palácio da Pena graces another, Monte Sereno is home to this remarkable neo-Gothic “castle,” originally built in the 1920s by renowned architect Norte Júnior. Crafted with a bold modernist concrete structure, the design embraces uneven modules, striking lancet windows, and battlements complete with guardhouses — a true architectural gem that seamlessly blends history with innovation.

The mansion later underwent a sensitive restoration by the distinguished Sessel family, who introduced elegant Art Deco influences that enhance the property’s timeless grandeur. Inside, expect soaring painted wooden ceilings, exquisite antique tiles, and dazzling Murano glass chandeliers that illuminate spacious interiors. Every window frames a captivating vista stretching from the rooftops of Lisbon to the distant sea, traversing the lush canopy of Sintra’s forested mountains.
