Ruine Hasenfratz

Burladingen, Germany, Germany

---

Ruine Hasenfratz, also known locally as Burgturm or Frazenhas, is the remains of a small medieval hilltop castle situated on a 839‑meter‑high hill above the district of Gauselfingen, which belongs to the town of Burladingen in the Zollernalbkreis of Baden‑Württemberg, Germany.

The fortress was built around 1150 and already abandoned by about 1250, with its original owners and builders remaining unknown, and the playful name “Hasenfratz” is thought to be a later nickname rather than a historical one. The site once had a core keep with a tower, additional buildings, a moat, and defensive walls, but today only the stump of the former tower and some scattered masonry and wall fragments remain, making it a quiet, wooded ruin rather than a fully restored castle.

The location lies on private land, so visitors can mainly see the ruins from the outside or along nearby paths, and it is often included in regional hiking routes that explore the many small castles and rock formations around Burladingen.
