The short answer
Seteais Palace in Sintra began as the mansion of Daniel Gildemeester, the Dutch consul who held Portugal's diamond export monopoly, built between 1783 and 1787 on land granted by the Marquis of Pombal. Later enlarged by the Marquis of Marialva and joined by a royal arch, it became a state-owned luxury hotel in 1954.

1783 to 1793
A Dutch diamond monopolist built his mansion here
You're standing at the gates of Seteais Palace, a pink Neoclassical palace in Sintra that now operates as a luxury hotel. Ahead of you is the older of its two wings, set on the edge of a hill with views across the Sintra mountains.
Daniel Gildemeester built this wing, the original home, between 1783 and 1787. He was the Dutch consul in Lisbon and held the exclusive right to export diamonds from Portugal, a monopoly granted to him by Sebastião José de Carvalho e Melo, Portugal's chief minister, known as the Marquis of Pombal. The minister had given Gildemeester the land itself.
Before that, Gildemeester had no house of his own in Sintra. He spent his summers as a guest in the minister's own palace nearby. He chose this hilltop for the view and built his mansion close to the home of his friend Gerard de Visme, the British consul, where the Monserrate Palace now stands. Gildemeester surrounded the new house with orchards.
Gildemeester died at the palace in 1793. By then he had already lost his diamond monopoly, a fall some tie to the death of King José I and the end of the minister's power. His widow kept the house a few more years before selling it in 1797 to Diogo José Vito de Menezes Noronha Coutinho, the 5th Marquis of Marialva.
1787 and after
An English writer visited as the Marquis's guest
The palace had hosted guests from its earliest days. The western wing's opening in July 1787 drew William Beckford, an English writer who later described Sintra's cliffs and gardens in his own travel writing. He stayed at the palace as Diogo's guest during the Marquis's years there.
1801 to 1802
A marquis joined two wings with an arch for a prince
Diogo set to work on the palace. He hired José da Costa e Silva, the architect behind Lisbon's São Carlos Theatre, to rebuild it.
In 1802, Prince Regent John and Princess Carlota Joaquina visited the palace. Diogo marked the occasion by joining the two wings with a neoclassical arch, built by the architect Francisco Leal Garcia. The arch carries bronze portraits of the royal couple and a Latin inscription. Walk through it and the towers of Pena Palace come into view across the valley.
Inside, several rooms were painted with frescoes credited to the French painter Jean-Baptiste Pillement, showing exotic plants and mythological scenes in the fashion of the day. They remain on the walls.
The palace's name has never been settled. Some say "Seteais," meaning "seven sighs," comes from an echo on the road below that repeats seven times. A different story in an old manuscript kept at the Sintra library traces it instead to "Centeais," after rye once grown on the land, which was known as the Campo do Alardo, a public field. A popular version ties the name to the Convention of Sintra, a treaty supposedly signed here in 1808. The treaty was actually signed at the Palace of Queluz. The confusion began in England, after London newspapers printed the agreement under the name "Convention of Sintra" without saying where it was signed.
1803 to 1946
The palace passed through marquises and dukes for generations
Diogo died in 1803. The palace passed down through his family and then through a string of other owners, among them the Dukes of Loulé and, by the 1890s, João Fernando Salazar e Bragança. It changed hands again several times over the following decades.
The Portuguese state bought the palace in 1946, ending more than a century and a half in private ownership.
1952 to 1954
Workers turned marquises' rooms into a hotel's suites
The Ministry of Public Works approved turning the palace into a hotel in 1952. Workers spent two years converting the rooms built for marquises and consuls into guest suites. The hotel opened in 1954, and it has run as one ever since.
1954 to now
Rock stars and film actors have slept where consuls once lived
Guests since then have included David Bowie, Mick Jagger, Johnny Depp and Brad Pitt. The hotel changed management in 2024, when the Valverde Group took over its operation after decades under the Tivoli brand.
The frescoes Pillement's followers painted still cover the walls of the old rooms. The arch Diogo raised for a prince still links the two wings.
The pink façade, the courtyard and the triumphal arch all stand as Diogo left them, now the entrance to a working hotel.

Prehistoric
Neolithic period
Just under 300 meters away, the Quinta da Penha Verde site has yielded evidence of a Neolithic settlement, among the oldest traces of people in the area.
The Castle of the Moors, a hilltop fortress with roots in the Islamic period, stands about a kilometer from this spot and anchors the oldest fortified ground in the town.
The great Lisbon earthquake of 1755 badly damaged monastery buildings and palaces around Sintra, including structures that became the later Pena Palace.
Daniel Gildemeester, the Dutch consul who held Portugal's diamond export monopoly, built the western wing of Seteais between 1783 and 1787 on land granted by the Marquis of Pombal.
After Gildemeester's death his widow sold the house to Diogo José Vito de Menezes Noronha Coutinho, 5th Marquis of Marialva, who enlarged it into the palace seen today.
In 1802 the Marquis of Marialva built a neoclassical arch, likely designed by José da Costa e Silva, joining the palace's two wings to honor a visit by Prince Regent John and Princess Carlota Joaquina.
The Portuguese state bought Seteais in 1946 and, with Salazar's authorization, converted it into a luxury hotel that opened in 1955 after a renovation designed by architect Raul Lino.
Roy Campbell, the South African poet, is buried at São Pedro de Penaferrim Cemetery, along with cartographer John George Bartholomew and architect Raul Lino, the man who redesigned Seteais into a hotel.
The land was granted to Daniel Gildemeester by the Marquis of Pombal, and before building his mansion between 1783 and 1787 Gildemeester had no house of his own in Sintra, staying instead as a summer guest at the minister's palace nearby.
Who built Seteais Palace?
Daniel Gildemeester, the Dutch consul in Lisbon who held the exclusive right to export diamonds from Portugal, built the original western wing between 1783 and 1787.
What happened at Seteais Palace in 1802?
The Marquis of Marialva joined the palace's two wings with a neoclassical arch, built by Francisco Leal Garcia, to mark a visit by Prince Regent John and Princess Carlota Joaquina. The arch carries bronze portraits of the couple and a Latin inscription.
Why is it called Seteais?
The name's origin is disputed: one story traces it to an echo on the road below that repeats seven times ("seteais" meaning seven sighs), while an old manuscript at the Sintra library instead derives it from "Centeais," after rye once grown on the land.
When did Seteais Palace become a hotel?
The Portuguese state bought the palace in 1946, the Ministry of Public Works approved its conversion in 1952, and the hotel opened in 1954 after two years of work turning its rooms into guest suites.
Was the Convention of Sintra signed at Seteais Palace?
No. The treaty was actually signed at the Palace of Queluz, though London newspapers printed it under the name "Convention of Sintra" without specifying the location, which helped tie the name to Seteais in popular belief.
