The Plaka Bridge, over Arachthos River, was the largest stone one-arch bridge in Greece and the Balkans, and the third largest one-arch stone bridge in Europe. Constructed by Constantinos Bekas in 1866, the bridge stood for 148 years only to be claimed by a flash flood in February 2015.
The Plaka bridge was built upon the order of Ottoman Sultan Abdülaziz. In the six years prior to its construction, two attempts were made by other builders. Both had proven unsuccessful, with the bridge collapsing during construction.
