Bildungshaus Schloss Puchberg, Education centre in Puchberg, Wels, Austria

Bildungshaus Schloss Puchberg is a Renaissance castle in Wels-Puchberg, built from 1595 for Christoph Puechner. Its north wing retains a round tower whose vaults date from the construction period, while the first floor of the south wing has richly ornamented stucco ceilings. Early Baroque onion domes crown the building, and the courtyard contains a Neptune fountain from 1740.

Christoph Puechner built the Renaissance residence from 1595; Emperor Matthias raised it to an Edelmannsitz on 9 November 1618, granting its owner subjects and lower jurisdiction. Around 1700 the Seeau family added a brewery, and in 1740 the courtyard fountain with a Neptune figure. Alfred Ritter von Jurnitschek had it remodelled in classicist style from 1880 to 1885 with architect Christian Lothary. The Diocese of Linz bought it in 1953 for 1.3 million schillings and opened a Catholic adult education home that year.

The educational institution offers programs in theology, philosophy, psychology, environmental studies, communication, and creative arts for personal development and learning.

The Bildungshaus is a seminar and education centre, not a hotel, so rooms and facilities are used by course participants. It stands in the Puchberg district in the south of Wels, with the Schloss courtyard, farm buildings and the Neptunbrunnen fountain (1740) grouped together. Visitors reach the historic rooms via the entrance hall and the staircase whose vaults date from the building's construction period.

The Schloss is owned by the Diözesane Immobilien-Stiftung, and since September 2023 Christoph Burgstaller has directed the Bildungshaus. The 1953 purchase by the Diocese of Linz for 1.3 million schillings required its own federal law, known as the "Lex Puchberg".
