History and context

Rock and masonry

The fortress occupies a diabase outcrop rather than a broad plateau. Its compact oval perimeter, projecting towers and narrow western gateway follow the available rock. The heritage institute records an enclosed area of roughly 650 square metres.

How long was it used?

Radivoj Kotromanić is recorded as owner in 1449. Later Ottoman service included repairs and artillery; the garrison finally left in 1840. These layers explain why medieval planning and later military work coexist in the ruins.

Timber traces inside stone walls

Soko’s masonry preserves holes associated with timber used in the walls. The Tuzla heritage institute distinguishes transverse medieval timbers from longitudinal reinforcement associated with Ottoman repairs. These small traces help explain how apparently continuous stonework can contain different construction phases. The same description identifies a compartment with a tufa vault but leaves its purpose unresolved pending archaeology. When looking closely at the ruin, a surviving opening or vaulted space should therefore prompt a question about construction and use, rather than an automatic label such as dungeon, chapel or storeroom.

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.
