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.
Edmund de Unger
The majority of carpets that form the core of the Keir Collection remain in the 18th century Manor House on Ham Street in Richmond, London, which was de Unger's home up to his death in 2011. A small but representative portion of classical oriental carpets from Persia, Turkey and Mughal India are on display in the Pergamon Museum of Islamic Art.
