Built on a Roman settlement, pottery dating from l,000 BC onwards has been found around the castle. Look for clues from the past in the remains of the Byzantine cisterns and Ottoman buttresses, and go to the ramparts for the best view. Since Kadifekale lacks informational displays, most travelers opt for a guided tour to understand the castle’s complicated history of occupation and conquest. Tack on visits to the Agora, and the Ethnographic and Archaeological museums for an appreciation of the region’s ancient past. Another option is a niche tour, such as a guided excursion to learn about Izmir’s rich Jewish heritage.
