Koprivnik Castle (Slovene: Grad Koprivnik, Vranja peč, German: Burg Rabensberg)[1] is a castle ruin above the village of Sveta Trojica, near Moravče in central Slovenia.
[1] The estate was inherited by the Hohenwarths, followed by the sisters of St. Clare from Mekinje.
[1] In 1930, the land surrounding the ruins was purchased by Senator Valentin Rožič [sl].
[1] Remains visible today include the foundations of a defensive tower and some walls; most of the rest of the structure is covered by detritus.
Much of the worked stone was recycled for the construction of nearby Holy Trinity Church.
