Site on Lake Van, eastern Anatolia (Turkey), which was the center of the Urartian state, c 850-600 BC. There is a large temple complex which was a Urartian fortress, storerooms, and residential area, including bronze, carved ivory, and silk artifacts. There are other temples, storerooms, etc. in the area in which some wall paintings remain. The walls of Toprakkale, erected in the 8th century BC, were of Cyclopean masonry and sloped slightly inward, perhaps as a defense against earthquakes. Artifacts show a high level of artistic achievement, in bronze, gold, silver, and ivory. Excavations have also uncovered a basalt floor inlaid with limestone and marble, parts of a decorated marble frieze, and brilliantly polished red pottery vessels. Toprakkale is also the name of a fine burnished red ware of the Urartian period.
