Burgstall Kraiburg, Medieval castle ruins in Kraiburg, Germany.

Burgstall Kraiburg is a medieval castle ruin on Schlossberg hill at 445 meters elevation, preserving only the foundation remains of a fortress from that era. St. Georg Chapel now stands where the fortress once rose, marking the historical center of the site.

The fortress was founded around 1100 by Count Engelbert II of Spanheim, who established it as the county seat through marriage to Uta of Passau. Damaged in conflicts over centuries, only its keep remained standing until administrative functions relocated in 1754, ending occupation of the site.

The name Burgstall is the German term for a castle site where no standing building survives. The hill is also recorded as a Bronze Age or Urnfield period hilltop settlement, so the same ground was used in two distant eras. The St. Georg chapel on the summit was built in 1838 as a votive chapel.

The site is easily reached on Schlossberg hill with information markers placed near St. Georg Chapel for orientation. Visitors should expect uneven ground as the ruins sit on a hillside, making sturdy footwear helpful for exploring the area.

The Bavarian monument register lists the site not only as a medieval and early modern castle but also as a hilltop settlement of the Bronze or Urnfield period, under file number D-1-7840-0017. The 1838 St. Georg chapel, a votive chapel, stands at the highest point of the 445 m Schlossberg.
