Sete Cidades
Lagoa das Sete Cidades is located at the top of the Sete Cidades caldera, in the parish of Sete Cidades, on the island of São Miguel, in the Azores.
The caldera was formed by successive collapses of stones and boulders, and has an area of approximately 4.3 km, maximum depth of 29 meters. It is one of the largest abatement boilers in the world. Its edges have, for the most part, very sloping and green slopes.
It is part of a mountain area with a very accentuated relief, with interior cliffs, deep ravines and souls, and furrows in whose beds torrential waters flow. Pico das Almas, 873 meters high, is the highest elevation in this area, and is named for the souls that hover there, as it was once a cemetery.
The zone includes an urban area, agricultural land and massive forests for the production of cryptomeria.
