You may remember that I once told you something about the Halligen in the North Sea? Those mini islands where sometimes there is only one house and they are regularly under water and only the house is still dry? Well, the inhabitants have to commute from the mainland to the Hallig with a wagon and that only works when the water is low. This is what the whole thing looks like .... a bit creepy, isn't it ?
The 98-kilometer Kiel Canal (Nord-Ostsee-Kanal) between the North Sea and the Baltic Sea begins at Brunsbüttel on the Elbe River, Germany. Locks are necessary at both ends of the canal to control the sea tides.
