Palais Trauttmansdorff, Baroque palace in Innere Stadt, Austria.

Palais Trauttmansdorff is a six-axis palace in the Innere Stadt with a stone entrance portal decorated with floral motifs and multiple interior courtyards. The building spans six window bays and preserves medieval cellar vaults beneath the later baroque layers.

The palace came into the possession of the Trauttmansdorff family in 1639, led by diplomat Maximilian von und zu Trauttmansdorff, and remained in their hands until 1940. In the late 18th century, the building underwent major redesign with the addition of an extra floor and the introduction of classical design elements.

The palace displays layers of different building periods in its facade and courtyards, shifting from baroque forms to classical details. You can see this evolution directly in the stonework and decorative elements as you move through the spaces.

The palace stands at Herrengasse 21, with Palais Batthyány at No. 19 and Palais Porcia at No. 23 as immediate neighbours, and the Freyung square just beyond. The Schenkenstraße wing was added between 1834 and 1838, so the building can be circled from two streets. Since 1966 it has belonged to the Niederösterreichische Brandschadenversicherung and is rented out, so visits are made from the street.

The cellar walls date from the Middle Ages, and a building on this spot is documented in records as early as the 14th century. The baroque palace above them was built in the mid-17th century, so the oldest masonry sits below the visible floors.
