Castle Lunenburg

Langbroek, Netherlands, Netherlands

---

Castle Lunenburg is a medieval tower house castle situated in Langbroek, Utrecht province, Netherlands, along the Langbroekerwetering waterway, first documented in 1339 when Arnold van Zijl adopted the name "van Lunenburg" upon establishing his residence there.

The original 13th-century stone keep evolved through ownership by families like Van Lockhorst and Van Lynden—who filled the moat and expanded it into a neoclassical residence by the late 18th century—before suffering severe World War II damage that prompted a 1968 restoration removing later additions to revive its historic form with a surrounding moat and wooden bridge.

Today, the rectangular tower connected to a modern house amid landscaped gardens attracts visitors during an annual June open day, hosting wildlife like kingfishers in its moat walls and storks in the upper sections.
