Pergamon Bridge
The Pergamon Bridge is a Roman substruction bridge over the Selinus river (modern "Bergama Çayı") in the ancient city of Pergamon (today Bergama), modern-day Turkey. The wide structure, the largest of its kind in antiquity, was designed during Hadrian's reign (AD 117–138) in order to form a passageway underneath a large court in front of the monumental "Red Basilica" temple complex. The two intact tubes, which consist of supporting walls covered with barrel vaults, still serve their purpose to this day.
Pergamon
During the Hellenistic period, it became the capital of the Kingdom of Pergamon under the Attalid dynasty in 281–133 BC, who transformed it into one of the major cultural centres of the Greek world. Many remains of its impressive monuments can still be seen and especially the outstanding masterpiece of the Pergamon Altar. Pergamon was the northernmost of the seven churches of Asia cited in the New Testament Book of Revelation.
