A hidden treasure in Sicily

Adranon, or Adranos, was an ancient city founded by Dionysius I of Syracuse around 400 BC. It was located near the Simeto River. Archaeological excavations in the 20th century uncovered the city's walls, built of basalt ashlar, and are in good condition on the east side. A steep ravine was used for the defense of the city on the south side, along the river. The existing rectangular tower is incorporated in St. Francis Church in the northeastern edge of the wall. Excavations have also unearthed a type of grave uncommon in Sicily, consisting of small circular structures in lava stone that are vaguely reminiscent of Mycenaean domes (tholoi).
