Portugal🇵🇹, Azores Islands
Corfu Island (port. Ilha do Corvo, literally —raven Island") is the northernmost island of the Azores Archipelago.
The island is low and very picturesque - in the north there is an extensive volcanic caldera Caldera about 300 meters deep and 2 km in diameter (in the center of the caldera there are two lakes with small islands in the middle).
