Schloss Neu-Wartenburg, Baroque castle in Timelkam, Austria.

Schloss Neu-Wartenburg stands on the right bank of the Vöckla below the old Wartenburg castle. The main house has a raised central section, and an east-facing cour d'honneur is framed by two side wings and a portal with pavilions. The dome over the centre was destroyed by fire in 1940 and rebuilt in 1968.

Johann Albert Graf Saint-Julien-Wallsee bought the Wartenburg estate in 1729 and had Anton Erhard Martinelli design this castle between 1730 and 1732, after inviting Emperor Charles VI to a three-day falcon hunt. Debts forced him to sell in 1754; the estate passed through the Ghelen, Grechtler, Reischach and Ratzesberg families before Albert Graf von Saint-Julien recovered it in 1869. A 1940 fire destroyed the dome, rebuilt in 1968.

The park, laid out in the bend of the Vöckla, still keeps the basic outlines of its 1730s design, while its outer areas were turned into a landscape garden in the 19th century. It is listed as a garden monument under Austria's heritage protection law (No. 27 in the annex to § 1 Abs. 12 DMSG). The castle and park are private and not open to visitors.

The castle remains in private ownership and is not open to the public, though it can be viewed from the outside. It is located in Timelkam in Upper Austria, reachable by car or regional transport.

The castle's park still shows the basic layout of the 1730s, with 19th-century landscape-garden elements in its outer areas; it is listed as a garden monument under Austria's heritage protection law (No. 27 in the annex to § 1 Para. 12 DMSG). The estate also includes scattered houses, and the farmyard at the far end of the avenue now belongs to the municipality of Vöcklabruck.
