Eichstädter Warte, Medieval watchtower in Langeneichstädt, Germany.

The Eichstädter Warte is a 15.6-metre watchtower on a hill near Langeneichstädt in Saxony-Anhalt's Saalekreis district. Its walls of limestone with some sandstone enclose a base circumference of 23 metres. The only entrance lies on the south side about 8 metres up, reached by ladder, and the viewing platform stands at 12 metres.

A fortified structure first appeared at this location during the 10th century under King Heinrich I to guard against Hungarian raids. The tower seen today was built later in the medieval period, reflecting how this defensive purpose remained important across generations.

The tower forms a monument ensemble with the nearby Neolithic Langeneichstädt megalithic tomb, discovered by chance in 1987. Its capstone was a menhir bearing a carving of a dolmen goddess, now displayed in the State Museum of Prehistory in Halle, with a replica standing between the tomb and the tower. The goddess is a station on the Himmelswege tourist route.

The entrance sits several meters above ground level and was historically accessible only by temporary climbing aids that are no longer permanently installed. Visitors should check the current accessibility conditions and any safety measures before planning a visit.

Wooden remains from the tower were analyzed using dendrochronology, a technique that reveals exact construction dates from growth rings. This study showed the current structure was built in 1483, pinpointing precisely when it was erected.
