The Kukuljević-Rajter' s Mill, notable even today for its imposing architectural size, was the second largest mill, right after Pust’s Mill, and stood out among the others. It is located right next to the Bistrica stream, and constructional traces of the dam in the streambed are still visible near the building. The original owner, since 1906, was nobleman Božidar Kukuljević, later succeeded by Franjo Reiter as the owner. Initially, the mill provided grinding services for all types of grain, but it was later modified for specialized milling. Locally, it is known as “Rajter’s Mill,” likely due to the change in ownership. Kukuljević’s Mill ceased operations in 1940. Subsequently, the building housed a cardboard manufacturing facility (“Kartonaža”) and a carpentry workshop.

Božidar Kukuljević Sakcinski

Božidar Kukuljević Sakcinski was born on March 31, 1861, in Zagreb, and passed away on January 19, 1927, in Ivanec. He was the son of the renowned Ivan Kukuljević Sakcinski and inherited the Ivanec estate with the castle from his uncle Ladislav in 1896, becoming a prominent landowner in Ivanec. Božidar gave the Old Town its final appearance, recognizable from postcards, and older residents of Ivanec recall its grandeur and beauty. He arranged an English-style park (now the town park) and furnished the living quarters with period furniture and artwork from his father Ivan's legacy, including original paintings by Vjekoslav Karas, portraits of Croatian historical figures, and other art pieces. By nature and inclination, he was an admirer of music and literature, writing poetry himself. He actively followed literary trends in Croatia, publishing reviews and critiques in literature during the late 19th and early 20th centuries.

Božidar Kukuljević Sakcinski was among the founders of the "Brotherhood of the Croatian Dragon" and served as president of the choral societies "Kolo" in Zagreb and "Vila" in Varaždin. He also founded the Ivanec branch of the Croatian Mountaineering Society in 1898.
