NABEUL, TUNISIA—Ruins of the ancient Roman city of Neapolis have been discovered off the northeast coast of Tunisia, according to an AFP report. Underwater archaeologists from the Tunisian National Heritage Institute and Italy’s University of Sassari have found streets, monuments, and some 100 tanks that were used to produce garum, a popular fermented fish sauce. “This discovery has allowed us to establish with certainty that Neapolis was a major center for the manufacture of garum and salt fish, probably the largest center in the Roman world,” said team leader Mounir Fantar. The city is thought to have been submerged during a tsunami in A.D. 365. For more, go to “Romans on the Bay of Naples.”
