Site in the Alban Hills, near Rome, Italy, where the remains of two ships were found which belonged to the emperor Caligula. These two Roman galleys rested on the lake bottom on the west side and were raided continually, with the ships finally raised in the 1920s. They were pleasure ships of the period of the emperor Caligula, one measuring 210 x 66 ft, the other 233 x 80 ft. Many of the objects found on the ships are in museums in Rome, but the ships unfortunately were burned by the retreating German army on May 31, 1944. Other excavations led to the discovery of the temple, one of the richest in Latium. The remains of the temple precinct - a large platform, the back of which is formed by a wall of concrete, with niches, resting against the cliffs - are situated a little above the level of the lake, on the northeast.
