The ancient Greek city of Pergamon situated 16 miles from the Aegean Sea on a lofty isolated hill. It existed at least from the bronze age, but it became important when it became the capital of the Kingdom of Pergamon during the Hellenistic period, under the Attalid Dynasty. The fortress and palace stood on the peak of the hill, while the town itself occupied the lower slopes. Under the Roman Empire the city was situated on the plain below. It was one of the Seven Churches of Revelation, and belongs to the top 100 historical sites of Turkey.
