The best walks and hikes around Roppenheim

Watching ships passing through locks is always interesting

From the bridge you can watch the lock operation. It is always fascinating to see how the heights are bridged.

The Iffezheim barrage is a barrage on the Upper Rhine that increases the navigability of the river and at the same time serves to generate electrical energy.

The lock at Iffezheim...interesting

great Rhine dam path

Main fort of Fort-Louis, former fortress In 1686, King Louis XIV of France ordered the construction of a fortress in Lower Alsace, directly on the border with the Margraviate of Baden. It was built over a period of ten years from 1687 on an island in the Rhine, which was not yet regulated at the time, according to plans by Sébastien Le Prestre de Vauban and the fortress engineer Jacques Tarade. The medieval palace in Haguenau, around twenty kilometers away, was razed to the ground and the usable stones were used to build the new fortress on the Rhine. Two outlying forts were built as bridgeheads on the opposite banks of the Rhine, Fort Alsace on the Alsatian side and Fort Marquisat on the Baden bank. To the south of the main fort, called Fort Carré, the regular street grid of the municipality of Fort-Louis was created on the island, and the king promoted its settlement with privileges. Fort Marquisat had to be abandoned after the Peace of Rijswijk in 1697, and finally after the Peace of Rastatt in 1714. The main fortress was stormed in 1793 in the First Coalition War and further destroyed in 1815-18. Since the Rhine was straightened in the 19th century, the fort and the municipality have been located on the left bank of the Rhine. Remains of the fortress are still there today, with information boards in front of and on the site of the former fortification.

French: Polder de la Moder Location: Lifting station on the Rhine, to flood the polder in the event of flooding via 6 lifting lines The Moder polder is a retention area to protect against flooding on the Upper Rhine at Rhine kilometer 330. It is located in the districts of the municipalities of Fort-Louis and Neuhaeusel in the Bas-Rhin department in the French region of Grand Est. The polder was created as part of the Integrated Rhine Program, which aims to restore protection against 200-year flooding on the Upper Rhine, which had been lost due to the construction of barrages on the southern Upper Rhine and the embankment of river floodplains. The polder is located above the Iffezheim barrage. The water level of the Rhine, which is surrounded by dams, is approximately six meters above the ground. The polder is named after the river Moder, which used to flow into the Rhine at the northern end of the polder. Today, the Moder runs parallel to the Rhine to the north and flows into the Moder below the barrage. The polder area, surrounded by a dyke, is predominantly wooded; over a third of the area is taken up by two quarry ponds. The polder, completed in 1992, has an area of 240 hectares, on which up to 5.6 million cubic metres of water can be retained. Up to 160 cubic metres of water per second can be channelled into the polder via six siphon pipes. The polder is operated by Voies navigables de France (VNF), the state waterways administration in France. The polder is emptied via the Rhine side ditch, which runs at the foot of the Rhine dam and flows into the Moder. There are also two weirs that connect the north of the polder directly to the Moder. When the polder is in use, the Rhine side ditch is blocked by a weir at the southern end of the polder. The outflow of the Rhine side ditch is then ensured by a ditch that runs inside the polder dyke to the Moder. The polder is used when the discharge at the Kehl-Kronenhof gauge exceeds 4200 cubic metres per second and at the Maxau gauge near Karlsruhe exceeds 4400 cubic metres per second. The polder is emptied when the discharge in Maxau has fallen below 4000 cubic metres per second. The outlet area of the Söllingen/Greffern polder is on the opposite, Baden side of the Rhine.

Depending on the wind direction, driving down on the road is less strenuous because it is somewhat protected from the wind. But it's nicer up on the Rhine.
