The heritage institute identifies a 25m oval foundation and traces of a round tower. The castle appears in thirteenth-century records as Gaj. Later frontier garrisons occupied it, but today its significance lies in archaeological remains rather than standing monumental walls.

What is left of the castle?
The heritage institute describes an oval foundation about 25 metres long and traces of a round tower about eight metres across. These dimensions describe a compact fort, not the separate, better-known castle at Velika Kladuša.
An older name in the records
The institute traces Gaj to thirteenth-century records. Later owners included the Frankopans of Slunj. An Ottoman garrison was established in 1633 under the Ostrožac captain’s deputy, continuing the site’s frontier role.
Names and the scale of the remains
Gaj, Donja Kladuša and Mala Kladuša are names connected by the heritage institute’s account of this site. They are useful search terms when following its history through different periods, but should not lead to confusion with Velika Kladuša. The surviving foundations are especially important because they offer a firmer guide to the footprint than any imagined roofline or tower height. A round tower about eight metres across occupied a substantial share of this compact enclosure. Viewing the plan from above helps convey that proportion without pretending the lost upper parts are fully documented.

Circular foundation
The source records an 8m-diameter round tower. Only its broken foundation is shown.
Oval circuit
The 25m-long footprint survives archaeologically. Its width and alignment here are estimates.
Missing fabric
Scattered masonry indicates loss, not a measured excavation or a reconstructed medieval interior.

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.
