Windhaag bei Perg is a market town located in the Perg District of Upper Austria, situated within the Mühlviertel region. It lies at an elevation of approximately 514 meters above sea level and covers an area of roughly 19.2 square kilometers.
The municipality is historically notable for its association with the composer Anton Bruckner, who lived and worked there as a primary school teacher and assistant organist between 1841 and 1843. The town maintains a memorial site and museum dedicated to Bruckner’s tenure, documenting his early musical development and professional life in the region.
Architectural landmarks in Windhaag bei Perg include the Parish Church of St. Mary Magdalene, a late Gothic building, and the ruins of Windhaag Castle (Burgruine Windhaag). In the mid-17th century, the castle was significantly expanded into a grand Renaissance palace by Count Joachim Enzmilner. However, following the Enzmilner family's decline, much of the palace was dismantled, and the materials were repurposed, leaving only the ruins visible today.
The local economy is primarily based on agriculture, forestry, and small-scale local businesses. The municipality consists of several rural subdivisions and cadastral communities, including Altenburg and Karlingberg. As a political entity, it functions as part of the judicial district of Perg.
