In the surroundings of the Römermuseum Osterburken, the UNESCO World Heritage Site Limes is preserved in some places on the site and can be visited. Only 300m away from the museum, the Osterburken fort is preserved as a park. The preserved walls and excavated ditches of the annexed fort, excavated between 1892 and 1910, give an impressive picture of the size of the ancient fortifications.
One highlight is the walk-in lime tower, located about 1km south of the city, visible from afar at an altitude. The replica shows the state of construction of the border complex in the 3rd century AD and is worth a walk. A watchtower and a piece of the Limes wall show the last stage of the Limes as a walk-in 1:1 model..
In the forest north and south of Osterburken the Limeswall is preserved for about 1,000m. The foundations of the watchtowers have been preserved in two places, while other towers can be discovered on the rubble hills in the forest.
