Hollókő () is a village in northern Hungary, located in Nógrád County. The village, which was constructed in the 13th century and developed in the 18th and 19th centuries, is a well-preserved ethnographic village of the Palóc people, with traditional wooden architecture and layout of buildings, farms, and orchards. Because of its exceptional preservation and testimony to rural life before the arrival of modern farming practices, the village was inscribed as a UNESCO World Heritage Site in 1987. The original village (now in ruins) was built just below the castle walls. The Ottomans captured the castle in 1552, and for the next 150 years, control alternated between Ottoman and Hungarian forces. At the end of the Ottoman era (1683), the castle and the village were finally abandoned, and the present town grew up in their place.
