Hamburger Wappen, Rock formation in Blankenburg, Germany.
The Hamburger Wappen consists of three vertical sandstone pillars that naturally resemble the towers shown in Hamburg's coat of arms. The structure forms part of the larger Teufelsmauer formation and stands out as a distinctive geological feature in the area.
The sandstone layers of the Hamburger Wappen formed around 85 million years ago during the Upper Cretaceous period. Tectonic movements later elevated these rock layers, creating the formation visible in the landscape today.
The formation serves as control point 74 in the Harzer Wandernadel hiking network, where visitors collect stamps as part of a long-standing regional tradition. This practice connects hikers to a local custom that has shaped how people explore the Harz landscape.
Access is via marked hiking trails starting from the parking area at Blankenburger Strasse 51 in Timmenrode. The trails are well-marked and provide straightforward access to the rock formation.
The formation sits directly next to the Kuhstall cave system, which is part of the same Teufelsmauer complex. Visitors can explore both the rock pillars and the adjacent caves in a single visit.
