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.
Alfred Messel
Messel had long been interesting in the design plan for the Museum Island and since 1907 had been developing plans for the Pergamon Museum. It remains to this day the monumental, austere three-wing neoclassical construction which he conceived but did not live to see realized as he died in 1909. It was constructed with slight modifications between 1910 and 1930 under the supervision of Messel’s close friend, the architect and city planning official Ludwig Hoffmann. The museum was badly damaged in World War II, and starting in 2010 modifications of the building will be undertaken as part of the master plan for Berlin’s Museum Island.
