Lagoa das Sete Cidades on São Miguel in Portugal is a twin-coloured lake filling a wide volcanic crater in the island’s western uplands, west of Ponta Delgada. The lagoon lies within the Sete Cidades Massif, a stratovolcanic complex that shapes the landscape of the Azores’ largest island.Sete Cidades Massif
A caldera landscape defined by water and rock
The setting of Lagoa das Sete Cidades is a broad, steep-walled caldera whose rim encloses forested slopes, pasture and the parish of Sete Cidades on the shore.caldeira was formed The volcanic depression spans several kilometres across and is part of a stratovolcano whose summit area has collapsed over geological time.summit caldera
Within this crater, the lagoon occupies much of the floor as a single freshwater lake, despite its divided appearance. The water surface lies at an elevation of about 259 m (850 ft) above sea level, surrounded by encircling hills that rise substantially higher and frame long views across São Miguel’s western third.surface elevation 259 m The lake itself extends several kilometres in length and a couple of kilometres in width, with a maximum depth given as around 33 m, making it the largest surface freshwater reservoir in the Azores.maior reservatório natural
The blue and green halves of the lagoon
Lagoa das Sete Cidades is distinguished by its two contrasting halves, known as Lagoa Azul and Lagoa Verde. The larger northern expanse is referred to as Lagoa Azul, while the southern sector is called Lagoa Verde, and together they form one continuous body of water separated by a narrow strait.Lagoa Azul and Lagoa Verde A road bridge crosses the dividing isthmus, turning the line between the two lakes into a defined vantage point for observing the colour contrast and the surrounding slopes.connected by a narrow strait
The blue and green tones have helped to embed Lagoa das Sete Cidades in Azorean folklore, with stories about a princess and a shepherd whose tears formed different-coloured waters. Beyond legend, the visual distinction reflects ecological differences between the two areas of the lagoon, which together form an important freshwater resource for São Miguel and a protected landscape recognised within Portugal for its natural value.largest one of its kind
Viewpoints, village and volcanic context
On the rim above the lagoon, Miradouro da Vista do Rei is a prominent viewpoint in the municipality of Ponta Delgada, offering an elevated perspective over the twin lakes, the parish of Sete Cidades and the enclosing caldera walls.Miradouro da Vista do Rei From this vantage point, the contrast between the blue and green sectors of the water and the patchwork of fields, forest and settlement around the shoreline becomes clear.
The wider Sete Cidades Massif contains lava domes, cones and maar structures that reflect multiple eruptive episodes and collapses over tens of thousands of years.post-caldera eruptions Within the caldera, the village of Sete Cidades lies close to the water, linking everyday life with the volcanic and lacustrine landscape, while the lake’s status as a major freshwater body has made it a key environmental feature of São Miguel and the Azores.
