Otto-Glöckel-Schule Linz, Protected historic school building in Linz, Austria.

The Otto-Glöckel-Schule is a school complex in Linz made up of several connected buildings. The oldest, the Dürnbergerschule, was built 1899–1902 by Gustav Steinberger with a late-historicist facade and a central risalit; Julius Schulte added the Knaben-Bürgerschule Waldegg in 1910/11, including a gymnasium wing on Pillweinstraße with a temple-like risalit and Doric half-columns facing Wienerstraße.

The school was built between 1899 and 1902 following designs by architect Gustav Steinberger as part of Austria's educational expansion. It suffered major destruction during World War II and underwent comprehensive reconstruction work from 1946 to 1968 to restore the damaged structures.

The complex carries the name Otto-Glöckel-Schule only since 1951, first for one part and later for the whole ensemble; Glöckel was a Social Democratic politician and school reformer. The individual buildings keep older names: Dürnbergerschule for the 1899–1902 double primary school, Waldeggschule for the Hauptschule that grew out of the Bürgerschule from 1927. A 1955 statue by Josef Thorak stands in the inner courtyard.

The school grounds are viewable from outside, though access to interior spaces is typically limited to school events or arranged visits. It is advisable to inquire about current visiting opportunities and any special viewing times before planning a visit.

In the inner courtyard stands a statue made by Josef Thorak in 1955, commemorating the air raid of 16 October 1944. Four bombs aimed at Linz Hauptbahnhof hit the school around 10:30, killing 31 pupils of the women's vocational school, a teacher and nine Volkspflegerinnen.
