Lupoglav Castle, situated at the intersection of important transportation routes near Učka and Ćićarija, represents a significant historical monument. Throughout history, the castle has been owned by various noble families, each of which left a distinct mark on its development. The Brigido family stood out the most in the 16th and 17th centuries, during which the castle experienced its most significant growth under their ownership. Through an analysis of available literature on Lupoglav Castle, the architecture and historical restoration of the castle are presented. The paper emphasizes the castle's importance as a symbol of medieval Istria and its impact on shaping the settlement into a town. The paper also mentions selected castles in Istria and compares them to Lupoglav Castle to better understand their architecture, cultural significance, and importance to the local community at that time. The new castle, constructed in the 17th century, boasts impressive architecture and cultural value; however, it is currently in a deteriorated state and its tourism potential remains untapped. Given all the aforementioned points, the aim of the paper is to explore the history and significance of Lupoglav Castle and to promote its valorization in order to preserve cultural heritage and stimulate tourism in the region.
