Wasserburg Zilly

Osterwieck, Germany, Germany

---

Wasserburg Zilly is a well-preserved medieval moated castle in the village of Zilly near Osterwieck, Germany, constructed by the Counts of Wernigerode at the start of the 14th century as a 30x30-meter core fortress with a fortified west wing for commercial purposes.

First documented in 1172 as "Xillingho" tied to a lost settlement called Zillingen, it evolved from 12th-century origins into a Renaissance castle by the 16th century, later repurposed as a surveying office and retirement home.

Maintained by a local preservation association, it welcomes visitors with guided tours, tea, and cake service from June to September, showcasing its impressive architecture amid the northern Harz countryside.
