Januševec Castle, Heritage castle in Prigorje Brdovečko, Croatia.

Januševec Castle is a two-storey classicist building of rectangular plan, built around 1830, with a central rotunda rising through both floors and capped by a dome. One facade carries a large loggia, two others have columned porticos. The architect is unknown; the Zagreb builder Angelo Chicco supervised construction, and Bartol Felbinger drew unrealised designs.

Built around 1830 for Baron Josip Vrkljan, a former finance minister to Marie Louise, Duchess of Parma and Napoleon's second wife, the castle was sold about a decade later to the French count Edgar de Troissereux Corberon, a participant in the Illyrian movement. It then changed owners frequently. During the Second World War, Ustaše forces mined it while withdrawing after the massacre at Hrastina.

The castle's name, Januševec, is tied to the estate in Prigorje Brdovečko where it stands. Its owners left a mark on Croatian culture: the French count Edgar de Troissereux Corberon, who bought it about a decade after construction, was a prominent participant in the Illyrian Movement. Today the building serves as a storage depot for the Croatian State Archives, so its rooms hold archival material rather than period furnishings.

Januševec Castle stands at the crossroads of the Zaprešić–Brdovec road and the road running north to Trstenik in Marija Gorica municipality. The building serves as a storage depot for the Croatian State Archives, so the interior is not open to tourists; the two-storey facade, the great loggia and the columned balconies are best seen from the road.

The castle was mined by the Ustaše during their retreat after the Hrastina massacre in World War II, then restored between 1962 and 1970. Since then it has served as a storage depot for the Croatian State Archives, and it is listed as protected cultural property under code Z-2251.
