Charles Bridge crosses the Vltava river in Prague. Its construction started in 1357 under the auspices of King Charles IV, and finished in the beginning of the 15th century.
The bridge is 516 meters long and nearly 10 meters wide, resting on 16 arches shielded by ice guards. It is protected by three bridge towers, two of them on the Lesser Quarter side and the third one on the Old Town side. The Old Town bridge tower is often considered to be one of the most astonishing civil gothic-style buildings in the world. The bridge is decorated by a continuous alley of 30 statues and statuaries, most of them baroque-style, erected around 1700. (From Wikipedia)
