At the foot of Gurghiu Citadel Hill is Rákóczi-Bornemisza Castle. It was built during the reign of Prince George Rákóczi between 1630 and 1646. The latter wanted a residence in the Gurghiului mountains. His love for hunting determined this choice. In 1717, the castle became the property of Vice-Chancellor Ioan Bornemisza. His descendants occupied the residence for 100 years. After the suicide of Rudolf of Habsburg in 1883, the castle returned to the State.
The location was then used as a forestry school for a period, then became a hunting museum, in which Sámuel Teleki's trophies are also displayed. New buildings were added over the centuries, including a chapel, a mill and finally a glass and porcelain factory at the end of the 19th century.
Now the castle is included in the list of national monuments of national interest protected by law. It is visited because of its unique character and its anchoring in the history of the region. It also hosts events, such as the Gurghiu Girls' Fair and the Ibanești Valley of the Kings Festival.
