Snežnik Castle, Renaissance castle in Lož Valley, Slovenia.

Snežnik Castle is a four-story building in the Lož Valley near Kozarišče, surrounded by a Renaissance-era wall. Its present look dates largely from the second half of the 19th century, when a story, two turrets, and a terrace were added. Grave markers from a Roman outpost at Šmarata are set into the facade.

Snežnik Castle is first attested in 1269, when Meinhard von Schneberg held it as a ministerialis of the Patriarchate of Aquileia. In 1393 William II von Lamberg bought a quarter-share, and his descendants gradually acquired the whole estate, giving the castle its Renaissance form. After the Lambergs came the Eggenbergs, Lichtenbergs and Schönburg-Waldenburgs; Prince Jurij Schönburg-Waldenburg remodelled it in the second half of the 19th century.

The rooms inside show how the Schönburg-Waldenburg family lived during the 1800s, with parlors and private chambers still furnished as they were then. Walking through reveals the daily world of nobility through its objects and arrangement.

The castle stands in the southwest of the Lož Valley near Kozarišče, on level ground rather than a rise, so no climbing is needed. It is open to the public as a museum from April to October, and the surrounding English-style park with its chestnut and linden avenues and two small artificial lakes can be walked on footpaths.

The castle caretaker guarded the estate during World War II and repelled looters, so the Schönburg furnishings survive intact. Grave markers taken from the ruins of a Roman outpost at Šmarata were built into the castle walls.
