Following the invasion of the Turkish army, the Frankopans cede the property to the king, who places a military crew there as the first line of defense against the Turks. Although Brinje was attacked on several occasions, it was never conquered. After the successful defense and the abolition of the Military Frontier, the fort slowly fell into disrepair, and the entrance tower and the two-story castle chapel of St. Trojstva, one of the most beautiful Late Gothic sacral monuments in Croatia.
