Casa de Santa Maria

Visitor's Guide

Casa de Santa Maria, Cascais

The exterior of Casa de Santa Maria

Commissioned by Jorge O’Neill (a Portuguese nobleman of Irish descent) for his daughter, this house was built in 1902 across the street from the family’s mansion (which is now the Condes de Castro Guimarães Museum). It followed a design by Raul Lino, the leading architect of the time, who wanted to create the most perfect example of a typical Portuguese house. The result is a romantic construction, with a garden and terrace facing the sea, a conical chimney inspired by those of the Sintra National Palace, and an interior covered with baroque blue-and-white tile panels salvaged from an old chapel and a convent in Lisbon.

Baroque tiles cover much of the interior

The house was a private residence for over a century, and welcomed many of the monarchs and illustrious personalities who spent time in Cascais after WWII. Those included the Dukes of Windsor, the Counts of Paris, Spain’s King Juan Carlos, Italy’s King Umberto II, and U.S. President Richard Nixon.
