Albanus lacus

The Oxford Classical Dictionary

Albanus lacus (mod. Lago Albano), 

‘Alban Lake’, a crater lake in the Albanus mons near Rome. Its wooded banks in imperial times were studded with villas, e.g. Domitian's. Lacking natural outlets, its waters reach the Rivus Albanus, and thence the Tiber, via a tunnel, 1,800 m. (1,968 yds.) in length, through the crater rim built c.397 bc. The Romans reputedly excavated this emissarium to ensure the fall of Veii which, an oracle prophesied, awaited the overflowing of the lake (Livy 5. 15–19). Actually their motive was to carry off the waters rapidly for irrigation purposes (Cicero (Marcus Tullius) De divinatione 2. 69); otherwise seepage through the porous subsoil would have waterlogged the districts below.
