Perge

Perga or Perge was once the capital of Pamphylia Secunda and currently lies in Antalya province. It houses well preserved ancient ruins from the period of ancient Rome and has been a home to Hittites in around 1500 BC. The city is about 18 km east of Turkey and has remains of what was known to the world as the most prosperous city of its times. Once you enter from the arch of the Roman Gate, you are greeted by the Hellenistic Gate as well as remains of the city wall.
The Romans arrived in Perge in around 188 BC and most of the historic sites are the courtesy of the Romans. The 15,000 seat theatre, gymnasium, bath, agora and necropolis make for interesting sights and are a reminder of the Roman era and later became a Byzantine center. The great theatre and the stadium of Perge are very much intact but it’s actually Hellenistic-Roman gate-towers that garner most attention because of its peculiarity. It is the only pre-Roman structure with walls. This gate consists of two towers with a horse-shoe shaped court behind them. These two towers guard the southern entrance to Perge. Moreover, you can also visit colonnaded main streets, which are quite close to Antalya. Many of the findings from this site are now stored at Antalya Museum. You can watch, go up close, and even touch the ruins! The site has an entrance fee of 20 lira and can be reached via AC03 bus from Antalya city center to Aksu province.
