Burg Spielberg, Medieval castle and art museum in Gnotzheim, Germany.

Burg Spielberg is a medieval stone castle set on a hill of the Hahnenkamm ridge near Gnotzheim in Bavaria, Germany. The complex consists of a four-story residential tower, a western defensive wall, and a walled courtyard that together form a compact fortified compound.

Spielberg Castle was built in the first half of the 12th century, as a charter of 20 August 1150 names Tibertus de Spileberc as a witness. In the 12th and 13th centuries it belonged to the castle system of the Counts of Truhendingen. After their line died out, it passed in 1363 to the Counts of Oettingen and later became the seat of the Oettingen-Spielberg line.

The castle gallery shows the Ernst Steinacker collection, including works by his wife Ingrid and their children Veit and Annette. Steinacker, a sculptor and painter from Wemding, shaped the entire complex with his family between 1983 and 1987, giving every room its own artistic treatment.

The art gallery inside operates on limited seasonal hours, but the castle courtyard stays open all year. Visiting outside gallery hours is still worthwhile, as the outdoor grounds can be explored freely.

The castle chapel is first documented in 1427, and between 1730 and 1735 Prince Johann Alois I of Oettingen had it and the three-storey main building refitted in early Rococo style. The sculptor and painter Ernst Steinacker, who shaped every room of the castle from 1983 to 1987, lies behind much of what visitors see today.
