The short answer

At Linhó, near Alameda do Linhó in Sintra, Portugal, Marcelo Caetano used a summer house from 1958 to plan his return to power after being forced from the Rectorship of the University of Lisbon in 1962. In 1968 he succeeded António de Oliveira Salazar as Prime Minister, holding the post until the Carnation Revolution of April 25, 1974 ended his government and Portugal's dictatorship.

1958 to 1968

A forced-out professor plots his return in a village house

Marcelo Caetano had already lost his job when he came to Linhó. He had served as a government minister under António de Oliveira Salazar regime. Then he worked as Rector of the University of Lisbon. In 1962 the Estado Novo regime forced him out of the university post. He had opposed police action against student protesters. He was a man without a title. He sat in a summer house in a small village on the edge of Sintra.

He did not stay out of politics. Starting in 1958, Caetano used the Linhó house to host meetings with allies. He planned his path back to power. For a decade, the house was less a retreat than a headquarters. A street in Linhó still carries his name. Attempts have been made to change it because of his ties to the dictatorship.

The plan worked. In 1968, Salazar suffered an incapacitating stroke. Caetano was named his successor as Prime Minister. The professor who had been forced from his university post became the head of the Portuguese state.

A man pushed out of one government spent ten years in a village house plotting how to lead the next one.
1974

A prime minister's fall closes the story begun at Linhó

Caetano's government fell on April 25, 1974. Army officers seized power in the Carnation Revolution. It ended 48 years of authoritarian rule in Portugal. It closed the story that had started sixteen years earlier in the house at Linhó. Caetano went into exile in Brazil. He died in 1980.

The village itself carries an older layer beneath that story. A quarter mile southwest of Caetano's house stands the Igreja da Penha Longa. A Hieronymite convent built this church in 1550. Ground there was first settled two centuries before that. Long before Linhó hosted a prime minister's comeback, it held monks in a walled retreat above the coast. The village has kept that pattern of quiet withdrawal ever since, whether the visitor wore a habit or held a portfolio.

1954 to now

A prison built near Linhó still holds young inmates

Withdrawal in Linhó did not always mean comfort. In 1954, the state built a prison on the edge of the village, in the parish that borders Alcabideche. It took the name Linhó Detention Center from the village next door. The complex spread across 90 hectares, close enough to share a name with the gated estates nearby. It still holds about 500 inmates, mostly young men between 21 and 30. Open-regime pavilions were added in 1994. A health unit opened in 1998. The same years saw Linhó's resorts and schools go up around it. Caetano planned a government's return from a house in this village. A short drive away, other young men have spent decades planning nothing but their release.

1956 to 1998

A diplomat's name marks a campus near Caetano's old house

The village kept building enclosures for people who could choose to be there. In 1956, American engineers worked on the Salazar Bridge. They needed a school for their children. The Carlucci American International School of Lisbon opened to serve them. It moved through several sites. Then Sintra's municipal government granted it land on permanent lease. The land sat near the Quinta da Beloura, one of Linhó's two gated communities. The new campus went up in 1997. Hillary Clinton, then First Lady of the United States, flew in to open it in 1998. The school later took the name of Frank Carlucci, the American ambassador who had worked to keep U. S.-Portuguese relations steady after the revolution that ended Caetano's government. A diplomat's name now marks a campus built where a fallen leader once planned his comeback.

Linhó has spent seventy years building quiet, guarded rooms for people other places would not shelter.
1999

A closed-door summit meets near a former dictator's planning house

In 1999, the Bilderberg Meeting convened at the Ritz-Carlton Penha Longa Resort, inside the Quinta da Penha Longa estate. The meeting draws politicians, bankers and executives from Europe and North America each year, and holds no public agenda and issues no communiqué. Attendees that year met behind the resort's walls. They sat a few minutes' drive from the house where Caetano once hosted his own closed-door planning sessions four decades earlier. No transcript of what was said there has ever been published. The estate that sheltered the meeting sits inside the same fold of hills that sheltered a prime minister's rise.

The gates in Linhó are still closed, and the village still keeps other people's business behind them.
