The Albaner See (Italian Lago Albano , also Lago di Castelgandolfo ) is a lake in the Alban Mountains of the central Italian region of Latium, southeast of Rome . It is often incorrectly referred to as the crater of a volcano , the complex of the Vulcano Laziale , but it is an intricately built maar that formed in the caldera of an ancient volcano. With a circumference of about 10 km it has an area of 6 km². The lake is up to 170 m deep. The water level of Lake Alban is regulated by an ancient drainage tunnel, which (supposedly according to a saying by the Oracle of Delphi ) was built in 398 BC. Was created. Lake Albano is separated from the neighboring Lake Nemi by Monte Cavo .
The so-called Artemisio-Tuscolana-Caldera , in which Lake Albano later formed, was formed during an eruption period with 6 large, explosive eruptions 560,000 and 350,000 years ago. The excavated volume was at least 280 cubic kilometers. New volcanic buildings and craters later formed in the crater basin as a result of phreatomagmatic explosions , and around 69,000 years ago today's Lake Albano was created by a maar explosion. Historical reports of eruptions in Roman times are uncertain, but seismic swarms with a duration of up to 2 years are certain. The last significant (as of January 2017) occurred in 1989 and 1990.
The lake's water level has sunk significantly since the mid-1990s. The reason for this is the large water consumption of the surrounding communities and the papal gardens.
The lake is named after the town of Albano Laziale , but the lake itself belongs to the municipality of Castel Gandolfo .
