Trajaneum (The Temple of Trajan) : The Trajan temple which was erected on a terrace measuring 68 by 58 m. carved from the hill was reflecting the characteristics of the Roman architectural styles. Due to space limitations on the hill top, the south part of the terrace was built on arched vaults and surrounded by a collonaded portico. The temple was built by Emperor Hadrian and dedicated to Emperor Trajan in the 2nd century AD. However both Emperors were worshipped here. The 6 by 9 columned, Korinthian order, Peripteros temple suffered much from several earthquakes and was in ruins. Restorations commenced in 1976.
