Bosanska Krupa Fortress
Known as Pset, the fortress occupies a prominent height in central Bosanska Krupa. The municipal visitor brochure records a thirteenth-century mention and notes repeated destruction and repair. The remaining towers and walls retain the outline of a compact fortified site within the modern town. Catholic and Orthodox churches and a mosque stand in the surrounding centre, illustrating how the castle belongs to a wider urban landscape rather than an isolated scenic island.

Architecture & evidence
Northern round bastion
Pset survives as compact masonry defenses on a summit within Bosanska Krupa. The round bastion is modeled roofless, preserving the open character of the remains instead of adding a hypothetical medieval roof.
Lower bastion and lookout
Low circular defenses and open visitor terraces shape the modern site. Timber lookout surfaces in this study represent visitor-era additions; their dimensions are approximate.
Climbing approach
The site belongs to the town's central landscape, overlooking the river and surrounding religious buildings. Stairs connect the lower path to the summit; the route geometry is interpretive and should not be used for wayfinding.
