Jajce Mithraeum
Roman-era temple to Mithra in Jajce, Bosnia and Herzegovina

The Jajce Mithraeum, or Jajački Mithraeum (Serbo-Croatian: Jajački mitrej) is a mithraeum, or temple of Mithraism. It was rediscovered in an archaeological dig in 1931 in Jajce, Bosnia and Herzegovina.
History
Mithra was worshipped throughout the Roman era, from the late Republic to the later Imperial era. The cult of Mithraism spread from the Middle East to other parts of the Roman Empire throughout the Mediterranean basin, at first by military-political adventurers, travelers, slaves and merchants from the Orient. Later, Mithraism was spread by soldiers whose legions came into contact with the followers of the cult in the East.
The temple dates back to the early 4th century, although it could be as ancient as the 2nd century with repairs undertaken during the early 4th century.
This particular Mithraeum is one of the best-preserved sites in Europe.
The Jajce site is a typical spelaea. Mithraism followers typically sought to set up their places of worship in caves. In the absence of such topographical features, they excavated the soil and built the small single-celled temple (spelaea) to reinforce the impression of a cave.

Why this record matters
The phrase “roman-era temple to Mithra in Jajce, Bosnia and Herzegovina” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Jul 18, 2026. The linked authority identifier is Q60745011. Authority coordinates are 44.341, 17.266. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1931.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
