Comporta and Melides: Rice, Thatch and the Alentejo Coast
Before it was a word for a style, Comporta was a rice estate.
South of Lisbon, beyond the Tróia peninsula and the estuary of the Sado, a low coast of dunes, pine woods and paddy fields runs down towards Melides. Comporta gave its name to all of it, and to a certain idea of summer. The place deserves a slower reading. It is an agricultural estate with a long history, a group of small villages, a vernacular of reed and thatch, a handful of remarkable contemporary houses, and, since January 2025, one of the strictest tourism planning regimes on the Portuguese coast. This guide sets out what to know, and what to check, before buying in Comporta or Melides.
Two municipalities, a string of villages
Comporta is first of all a civil parish of Alcácer do Sal, at the base of the Tróia peninsula, on the edge of the Sado estuary. Its villages include Comporta itself, Carrasqueira, Torre, Possanco and the two Brejos da Carregueira. To the south, the coast passes into the municipality of Grândola, with the parishes of Carvalhal, where Pego lies, and Melides. What the market calls Comporta is therefore spread across two municipalities, each with its own master plan and its own planning office.
Melides closes the stretch to the south. Its lagoon is separated from the Atlantic by a bar of sand, which the Portuguese Environment Agency opens to the sea once a year, as part of an annual plan, so that the water of the lagoon can be renewed.
An estate of rice
The Herdade da Comporta covers some 12,500 hectares. It belonged to the House of Aveiro and later to the House of the Infantado, and in 1836 it was sold to the Companhia das Lezírias do Tejo e do Sado. In 1925 it passed to the Atlantic Company, a British-owned firm registered in Jersey. Rice had been tried here since the eighteenth century, but it was the Atlantic Company that made it the estate's crop. It also replaced the cubatas, the thatched huts in which workers lived, with houses in better conditions, and built granaries, offices and a school. The rice-husking factory of 1952 is today the Museu do Arroz.
In 1955 the estate was bought by the Espírito Santo family. After the collapse of the group in 2014, the assets of the Herdade's real estate fund were sold, and the deed was signed in November 2019 with a consortium led by Vanguard Properties and Amorim Luxury. The paddy fields remain, and so does the scale: much of the land around the villages belongs to a few large estates.
Reed, thatch and timber: the coast was built with what grew on it.
Thatch, reed and stilts
The vernacular here is light. Fishermen and rice workers built with timber frames, reed and straw, and the thatched roof is the image the region has kept of itself. At Carrasqueira, on the estuary, the fishing community built by hand, in the 1950s and 1960s, a pier on irregular wooden stilts, a maze of walkways and landing stages for its boats. It is still used by some fifty fishermen. Storms partly destroyed it in early 2026, and the fishermen's association and the parish council have appealed for help to rebuild it.
Two houses by Aires Mateus
Two small projects have done much to make the architecture of the area known abroad. The Casas na Areia, near Comporta, completed in 2010 by Manuel and Francisco Aires Mateus, converted a group of old fishermen's houses into four volumes: two of masonry, two wrapped in timber. Their roofs are thatched in layers of straw held by boards, a traditional technique of this Atlantic coast, and sand is the floor of the common pavilion. The project was shown at the Venice Architecture Biennale in 2010. In 2013 the same practice built the Cabanas no Rio, two cabins with a total of 26 m² beside a wharf, in reclaimed timber left bare inside and out.
What these houses share with the older buildings is restraint: low volumes, natural materials, little ground taken from the dunes and the pines. It is a useful measure for anyone who plans to restore or build here.
What to check before buying
Much of the land is protected. The dunes and pine woods between Comporta and Galé form a Natura 2000 site, the ZEC Comporta-Galé, and the Sado estuary has been a nature reserve since 1980. Plots can also fall within the national ecological reserve (REN) or the agricultural reserve (RAN), which restrict building. Ask the municipality for the planning status of each plot before signing anything.
On the Grândola side, the first amendment to the municipal master plan came into force in January 2025 (Aviso 1869/2025/2). It created a zone of high tourism pressure on the coast, around Carvalhal and Melides, in which the only new isolated tourism developments allowed are campsites and caravan parks. It also banned new tourism development nuclei and set transitional rules for pending applications. The terms of reference of the amendment explain its reasons. In practice, a licence already granted is worth far more here than an intention to build.
Check, building by building, what each one is licensed for: a house, a rural tourism unit or local lodging are different things, with different rules (see our note on local lodging and rural tourism). Check water, often from a private borehole, and wastewater. For the purchase itself, see our guide to buying property in Portugal, step by step, and for a property that is many buildings at once, our guide to buying a village.
Seasons
The coast lives by the summer. July and August fill the beaches, the restaurants and the roads from Lisbon; the rest of the year is quieter, and the paddy fields, the estuary and the pine woods come back to the foreground. For a buyer, both seasons matter: one tests access and privacy, the other tests whether a house works as a place to live, or as a place to receive guests outside the high weeks.
Wiseguys Properties is selling the Casetas de Melides, 12,695 m² of land with olive trees, a licensed three-bedroom house, six independent timber cabins, a shared kitchen pavilion and a 12.5-metre pool, some 7 km from the beaches of Galé and Aberta Nova. For another house by the Atlantic, read about the villa at Areias do Seixo. To sell a property on this coast, contact us.
Frequently asked questions
Where is Comporta?
On the Alentejo coast, south of Lisbon, at the base of the Tróia peninsula. Comporta is a parish of Alcácer do Sal; Carvalhal and Melides, to the south, belong to Grândola.
Who owns the Herdade da Comporta?
The estate belonged to the Espírito Santo family from 1955. In November 2019 the assets of its real estate fund were sold to a consortium led by Vanguard Properties and Amorim Luxury.
Can you build in Comporta and Melides?
It depends on each plot. Natura 2000, REN and RAN restrict building, and since January 2025 Grândola's master plan limits new tourism developments in Carvalhal and Melides. Ask the municipality first.
Can I run rural tourism or local lodging in Melides?
Only with the right licence for each building. Check what is already licensed before you buy; new isolated tourism developments are now very limited in Melides.
How far is Melides from Lisbon?
About an hour and a half by car, depending on traffic.
