Architecture & evidence
Royal portal
The surviving 15th-century portal bears the Kotromanić coat of arms. This simplified opening indicates its role; carved decoration is not reproduced.
Defensive enclosure
The commission records an irregular quadrilateral, a 260 m circuit and walls about 1.75–2.05 m thick. This study simplifies their alignments.
Powder magazine
The heritage agency identifies a later powder magazine within the fortress. Its position and form here are interpretive.
