Miller-von-Aichholz-Schlössel, Protected heritage mansion in Penzing, Vienna, Austria

The Miller-von-Aichholz-Schlössel is a two-storey, elongated baroque building with a high hipped roof and dormers, located at Linzer Straße 429 in Penzing. Its garden front has shallow central projections and a raised central section with a three-axis arrangement, preceded by an external staircase with sturdy corner pillars. The upper-floor halls have mirrored ceilings and delicate stucco frames, and the state rooms contain original tiled stoves with rocaille decoration.

Around 1750 Empress Maria Theresia gave the Hütteldorf estate to Baron Johann Georg von Grechtler, who had a hunting lodge built to plans by Johann Bernhard Fischer von Erlach. Through Grechtler's heirs it passed to a Princess Esterházy, born Princess Liechtenstein, whose family used it as a summer residence for over a century. In 1894 Dr. Heinrich von Miller zu Aichholz bought the estate; the family sold it to the state in 1938.

The name reflects the Miller-von-Aichholz family, who shaped the estate over many decades through their ownership and use. Today it remains a venue for celebrations and gatherings, continuing Vienna's tradition of formal social events held in grand country residences.

The grounds offer both indoor and outdoor spaces for various occasions, with ample parking available. Note that this is primarily an event venue, so advance arrangements or bookings may be needed to visit.

In 1846, Archduke Franz Karl of Austria shot the last wolf roaming the Wienerwald forest on this estate. This rare hunting event marks when large predators finally disappeared from Vienna's surrounding woodlands.
