Schloss Primmersdorf, Heritage castle in Raabs an der Thaya, Austria.

Schloss Primmersdorf is a baroque building in the hamlet of Primmersdorf, part of Raabs an der Thaya in the northern Waldviertel. Its irregular one- to two-storey four-wing layout, altered by later conversions, is surrounded by service courtyards and a park laid out in 1860. The three-storey baroque design with volute gables on the long sides is attributed to Jakob Prandtauer. The grounds also hold the Schüttkasten, a granary built in 1706.

The castle was built in the mid-17th century to replace a medieval fortress that stood on the site since the 13th century. From 1696 to 1851 the property belonged to Herzogenburg Abbey.

The granary on the castle grounds, built in 1706, serves as an exhibition space and event venue since 1993.

The castle stands in the hamlet of Primmersdorf, part of Raabs an der Thaya in the northern Waldviertel. The irregular four-wing complex is surrounded by farmyards and a park laid out in 1860. The site is privately owned and restored, with apartments and an art studio; the Schüttkasten is used by the association Schüttkasten Primmersdorf for exhibitions and events.

A grain warehouse built on the castle grounds in 1706 has operated as an exhibition space and event venue since 1993. This protected building reveals how the site once functioned as an agricultural and economic center.
