Agger Weir near Troisdorf

Highlight • Structure

Here the agger is dammed up to supply the man-made mill ditch with water.

Tip by

In the Siegauen you drive, if one of the wind does not stop, relatively relaxed on the flood dam of victory and had a nice view of the area. Long-distance views to the Siebengebirge and the Eifel or Cologne Bay.

Nice little harbor. The ferry is not far from Mondorf. When the weather is good there is of course a lot going on there.
