Schloss Achleiten bei Limbach, Historic castle in Strengberg, Austria.

Schloss Achleiten bei Limbach is a castle in the hamlet of Achleiten, part of Limbach in the market town of Strengberg, Lower Austria. Built between 1727 and 1734 for Abbot Gregor I Plaichshirn of Tegernsee, it replaced an earlier fortified complex near the Danube that was prone to flooding. The baroque building stands on the site of a former farmhouse and is surrounded by a park.

The current castle was built between 1727 and 1734 on the orders of Abbot Gregor I Plaichshirn after flood damage threatened an earlier location. Moving to higher ground allowed the monks to maintain their summer residence safely for many years.

The castle was home to a monastic community for generations and still shows traces of this religious past. The layout and preserved details speak to how monks once lived and worked here.

The castle is privately owned by the Weichs family and cannot be visited inside. It stands northwest of Limbach, a cadastral community of Strengberg, and the building can be seen from the surrounding lanes. The park also passed to the Theurer family in 1982, who had the buildings and fittings restored.

The castle's chapel was dismantled in 1836 on the orders of Baron von Blomberg and its religious items were moved to the local kindergarten chapel. This unusual fate shows how the use of historic buildings can change dramatically over time.
