Strmol Mansion is a 15th-century manorhouse located on a low hill above the old town center of Rogatec, Slovenia. It is notable as one of the few castles in Slovenia to have retained a Slovene name throughout its history.
The mansion was first mentioned in 1436 as a simple fortified tower in the possession of the counts of Celje, who gave it in fief to Jakob Strmol of Cerklje. The tower became the core of the later manorhouse, and is partially preserved within the later additions, beginning with a second tower and defenses added in the 16th century. At the end of the 16th century, the castle was purchased by the Auersperg family, from whom it later passed to the Frankopans.
