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.
Parchment
The word parchment evolved (via the Latin "pergamenum" and the French "parchemin") from the name of the city of Pergamon which was a thriving center of parchment production during the Hellenistic period. The city so dominated the trade that a legend later arose which said that parchment had been invented in Pergamon to replace the use of papyrus which had become monopolized by the rival city of Alexandria. This account, originating in the writings of Pliny the Elder ("Natural History", Book XII, 69–70), is dubious because parchment had been in use in Anatolia and elsewhere long before the rise of Pergamon.
