Travel in Weekend #33 Link Party

Today in my Link Party - Travel in Weekend - a sluice on the River. Sluice in Bydgoszcz, Poland, on the river Brda. Always delighted me these structures, as it cleverly invented. In the picture you can see that the river at the back is higher by about 4-5 meters. The sluice ships can be raised or lowered to an appropriate level. Fantastic.

If you have interesting photos (and certainly you have) places that are worth visiting cities or wild areas, churches, buildings, bridges and old towns, I invite you.
