The Captain’s Tower preserves a prominent piece of Bihać’s former defences. Its precise foundation date is disputed: the cantonal heritage institute dates the current building to the beginning of the eighteenth century, while other accounts propose earlier origins. The model does not resolve that debate by inventing medieval fabric. Following the Austro-Hungarian occupation in 1878, the interior was adapted into a district prison in 1889. The tower later became a museum. The scene focuses on the surviving roofed stone tower, rather than reconstructing the lost city walls or treating the legend of King Béla IV as established history.

Architecture and interior life
The heritage institute describes a square limestone tower with a four-sided roof and walls tapering upward. Painted plant ornament found around an upper window suggests a reception room, although that room’s identification remains an interpretation rather than certainty.
Different uses over time
Adaptation into a district prison took place in 1889. Later interior changes altered the number of floors while preserving the exterior appearance. The building’s museum use is another chapter in this history; today’s interior cannot simply be projected back into its garrison period.
A carved bird in the masonry
A particularly small detail carries a larger question at the Captain’s Tower. The heritage institute records a relief of a pelican on an exterior stone and mentions the interpretation that the block was reused from a demolished building in Bihać. It does not establish which building supplied it. Such reused material can preserve an older object's history within a later structure. When comparing the tower with photographs, look beyond its overall shape to individual carved blocks; their presence does not mean all the surrounding masonry belongs to the same date.

How to read this history
A first written mention is not necessarily a construction date. Fortresses were often altered over several centuries. Sections link to their supporting references; the 3D model is an interpretation, not evidence of every historical phase.
