Altenburg Abbey

Altenburg Abbey is a Benedictine monastery in Lower Austria near the town of Horn, with a history reaching back to the medieval period and significant Baroque-era rebuilding of monastic buildings and the church.

The site is an active monastery complex and also contains architectural features from later renovations; visitors can see the abbey church and interiors that combine medieval origins with 18th-century Baroque alterations.

The community maintains liturgical functions alongside museum and visitor arrangements that present the abbey’s art and history.

Geographically the abbey sits in the Waldviertel region of Lower Austria close to the municipality of Altenburg and the administrative town of Horn.

• Visitor access: Today the abbey survives as an evocative ruin with visible church and cloister fabric and is accessible to visitors via local footpaths and minor roads near the Omberg area.
