A lot of work was done with the aid of water power. You can see the water wheel in the background. But also, the Vltava river would often flood. There are many markers in the area showing the height the water reached.
The Charles bridge is both famous and very busy with vendors and musicians.
Along the way are many statues. They are being ruined by air pollution. So slowly, the statues are being cleaned and preserved in a museum with copies being put in their place on the bridge.
