Strabo records that only a small part of Smyrna was located on the mound, with the greater part centered around the harbor on the flatlands below. The
stadium and the
theatre on the other hand, were on the slopes immediately below the summit. The settlements on the hill and those near the coast had a separate history in certain periods, as it was the case during the 14th century, when the hill castle was captured by the
Aydinids, and the port city, with another castle, was held by the
Genoese until its capture by
Tamerlane in 1403. During the 19th century, Kadifekale was part of the chain across several slopes which constituted İzmir's Turkish core, while the urban center below was the cosmopolitan part. The present walls are medieval. A number of sources put forth claims on having observed fragments of Hellenic masonry under the existing walls, but these fell short of having acquired general acceptance. The long hollow west of the castle marks the site of the Stadium, scene of the martyrdom of
St. Polycarp, and it is now completely built over. This is also the case for the ancient theatre of Smyrna, which is located to the east of the castle gates, although there a few traces are still visible to the naked eye. Both works belong to a reconstruction following a calamitous earthquake in 178. Next to the castle are the ruins of the
cisterns built during the Roman period and renovated during the
Byzantine and
Ottoman periods. They formed the centre of the drinking water network of Smyrna. The remains of this network are still preserved in the
agora of Smyrna in downtown İzmir. == Cultural activity ==
