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
The first mention of Pergamon after ancient times comes from the 13th century. Beginning with Ciriaco de' Pizzicolli in the 15th century, ever more travellers visited the place and published their accounts of it. The key description is that of Thomas Smith, who visited the Levant in 1668 and transmitted a detailed description of Pergamon, which the great 17th century travellers Jacob Spon and George Wheler were able to add nothing significant to in their own accounts.
