Stift Wilhering is a Cistercian monastery. The buildings re-constructed in the 18th century, are known for their spectacular Rococo decoration.

The monastery was founded by Ulrich and Kolo of Wilhering, who donated their family's old castle for the purpose, in accordance with the wish of their deceased father, after the family had moved to their new castle at Waxenberg. It was settled initially by Augustinian Canons, but in the first years the new foundation was beset with problems. On 30 September 1146, Ulrich replaced the canons with Cistercian monks from Rein Abbey in Styria.

Today the abbey's business enterprises—mainly forestry, farming, and greenhouses—provide a sound economic basis for the monastery. Kürnberg Forest (Kürnberger Wald), owned by the abbey and situated between Wilhering and Linz, forms a green belt that is highly beneficial to the people of the region.
