River Arachtos, between the county of Ioannina and Arta, is crowned by the bridge of Plaka.

Plaka Bridge is stone and arched, having only one arch with 40 meters length and a maximum height of 19 meters. Based on these characteristics, it is considered to be the largest of its kind not only in Greece but throughout the Balkans.

A bridge in this exact location had started to be built in 1863, yet it collapsed in its inauguration day. The current bridge was built in 1866, with donations and labor from local residents. According to local legends, in order to make the bridge stable and avoid another collapse, the people decided to bury in the foundations a human; some say a Turk and others a local girl. In 1881, when Arachthos became the border between Greece and Turkey, a customhouse operated next to the bridge on the Greek side.

Plaka Bridge is maintained in very good condition today, drawing the attention of each visitor.
