In the Lobau, an obelisk-like monument commemorates Napoleon I's headquarters during the 1809 campaign. In the spring and summer of that year, Napoleon used the Lobau as a strategic location to coordinate his troops in the lead-up to the Battle of Aspern, which took place on May 21 and 22, 1809, and became one of Napoleon's rare military defeats. The monument itself bears an inscription plaque highlighting the historical significance of the site and is part of the Napoleon Trail, which leads to several memorial stones and historical sites in the Danube floodplain. Visitors can not only gain insight into Vienna's military history but also experience the natural surroundings of the Lobau with its riparian forests and waterways, which were considered strategically important then as they are now.

Napoleon camped here with approximately 75,000 soldiers before suffering defeat at the Battle of Aspern. Then, as now, there are unfortunately too many rulers interested in war.

Unfortunately, cycling below the dam in the Lobau has been prohibited for the past two years. There are also exorbitant fines.

The Danube-Auen National Park is one of the last large, intact floodplain landscapes in Central Europe. It stretches along the Danube between Vienna and Bratislava and covers an area of around 9,600 hectares. The national park protects this unique river landscape, which is characterized by a dynamic interplay of floods, gravel banks, old watercourses and floodplain forests. The national park was created after the successful protests against the construction of a hydroelectric power plant in Hainburg in the 1980s. The protection of the floodplains became a milestone in the Austrian environmental movement. The Danube flows largely unregulated in this section, which means that natural flooding and changes in the course of the river remain possible. This dynamic creates diverse habitats.
