Schwarzenberg Navigational Canal
The thought of connecting the Vltava river with the Dunaj river, the flow of two rivers which lead into different seas, came about in the middle of the 14th century, during the reign of emperor Karel IV.
The actualisation of this project only came towards the 18th century.
For this reason the Schwarzenberg canal was built, one of the most unusual water constructions of its time. The new water way enabled the floating of timber from the Šumava region to its place of transport in Vienna, which made possible to utilisation the natural rich resources of Šumava forests which were up to then inaccessible.
