Schloss Trautenfels, Castle museum in Stainach-Pürgg, Austria.

Schloss Trautenfels is a rectangular Baroque palace on a rock spur above the Enns at 673 m, at the foot of the Grimming. Count Siegmund Friedrich von Trauttmansdorff had it rebuilt in its present form between 1670 and 1672. It has roofed inner courtyards, a tall tower, a free-standing chapel and five bastions; the first floor holds a festival hall with frescoes by Carpoforo Tencalla and stucco by Alexander Serenio.

First documented in 1260/62 as Neuhaus, a Salzburg-held toll post at the Salzstrasse crossing; Abbot Heinrich of Admont seized and largely destroyed it in 1289. The Hofmann von Grünbühel added Renaissance frescoes, likely painted in 1563 for Ferdinand Hoffmann's wedding to Margarete von Harrach. Count Siegmund Friedrich von Trauttmansdorff bought it in 1664 and rebuilt it in Baroque form between 1670 and 1672, when it took the name Trautenfels.

The castle houses extensive collections showcasing regional art, natural history, and cultural artifacts through its museum operated by Universalmuseum Joanneum, including the famous Marble Hall with frescoes by Carpoforo Tencalla.

Visitors can explore the castle through guided tours available in multiple languages, with facilities including parking areas, accessible pathways, and seasonal exhibitions displaying over 40,000 historical artifacts.

A few metres west of the castle, on the same ridge, stand the excavated foundations of the Protestant church of Neuhaus, once the most important religious centre of the upper Ennstal during the Reformation. The castle lords built it; the Counter-Reformation destroyed it. The remains were uncovered in 1991 and laid out as a memorial.
