The short answer

Casa de Santa Maria in Cascais began in 1902 as a wedding gift from Jorge O'Neil to his daughter, built by architect Raul Lino using only Portuguese materials in a Moorish-influenced style. Later owned by the Espírito Santo banking family, it was bought by the Municipality of Cascais in 2004 and opened as a museum in 2007.

1902

Jorge O'Neil had Raul Lino build a Portuguese-only house

Casa de Santa Maria is now a historic house museum, set near the sea in Cascais. Its rooms still carry blue and yellow tiles, horseshoe arches, and a painted ceiling from past owners. The house began in 1902, built for Jorge O'Neil, a wealthy aristocrat with business ties across Portugal. He had already built the Condes de Castro Guimarães Museum nearby. Soon after, he commissioned this smaller house as a wedding present for his daughter.

Jorge O'Neil hired Raul Lino, a young architect who got his start designing houses for friends in Cascais. For this house, O'Neil gave Raul Lino an unusual rule, telling him to ignore the fashionable European styles of the day. Instead, Raul Lino could use only materials found inside Portugal.

The result leaned heavily on Moorish design, the building style that shaped many of Portugal's grandest old buildings. Inside, horseshoe arches link the main rooms, a direct nod to that influence. The house took its name, Santa Maria, from the nearby cove and chapel grounds where O'Neil had already built his first house.

By the time it was finished, Casa de Santa Maria stood as one of the earliest examples of what became known as Raul Lino's Portuguese house style. Raul Lino would spend his career developing that style further, and this house was where it first took shape by the sea.

1917

The architect's brother filled the house with Portuguese tiles

Around 1917, the house passed to José Lino Júnior, an engineer and the older brother of the architect who designed it. José Lino Júnior was a serious collector of Portuguese art, and he set about filling the house with pieces he loved.

José Lino Júnior bought a set of 17th-century tiles from an old chapel in Frielas, a small village outside Lisbon. Along with the tiles came a wooden ceiling painted in oil, a work credited to António de Oliveira Bernardes, and José Lino Júnior had the ceiling adapted to fit the dining room. José Lino Júnior also expanded the house itself, adding new sections at each end. Raul Lino designed that expansion too, keeping the additions in step with the original house.

1934

Bankers hosted kings and a duke who gave up his throne

In 1934, the house changed hands again, bought by the Espírito Santo family, one of Portugal's most powerful banking families. Under their ownership, Casa de Santa Maria became a stop for European nobility and visiting heads of state.

Guests included Charlotte, Grand Duchess of Luxembourg, and King Umberto II of Italy, the last king to rule before Italy became a republic. The Duke and Duchess of Windsor also came through, the former King Edward VIII of Britain and the American woman he gave up his throne to marry. Former US President Richard Nixon visited as well. A family member added two stone sphinxes to guard the doorway.

2004

Cascais bought the house and opened it as a museum

In October 2004, the Municipality of Cascais bought Casa de Santa Maria from the Espírito Santo family. The deal brought a private home of nearly a century into public hands for the first time since Jorge O'Neil built it. The town spent the following years restoring the house, and it reopened to the public in 2007 as a museum.

Visitors today walk through rooms with no furniture, since the house was emptied before the sale. What remains are the walls themselves. The ground floor still carries the blue and yellow tiles José Lino Júnior brought from Marvila Convent in Lisbon. Upstairs, a small chapel holds tiled scenes from the life of the Virgin Mary, made in Talavera, Spain, in the late 1500s. Floral patterns painted on the chapel ceiling are Raul Lino's own work. Next to the chapel, the Great Hall keeps its painted ceiling and tiled walls intact. Down in the basement, visitors find modernist tiles from around 1920, also designed by Raul Lino, a sign of how far his style traveled from the Moorish arches he began with here in 1902.

Casa de Santa Maria stands open to the public as a museum, its tiled rooms and painted ceilings kept much as past owners left them.
