The mithraeum in Konjic was a temple dedicated to God of the Sun, Mithra.

The god was worshiped and cult of Mithraism spread to other parts of Roman Empire, throughout the Mediterranean basin, by slaves and merchants from the Orient, and by Roman soldiers who came into contact with the followers of the cult in the East.

This means that temple main characteristic is absence of cave, hollow ground or even constructed spelaea.

The Mithraism followers sought as a norm to found their places of worship in caves, whereas in absence of such topographical features they would excavate the soil, where the terrain permitted, and built small single-celled temple, known as spelaea, to reinforce the impression of a cave.

However, in case of Konjic, temple was established on open ground, and only protection and seclusion was provided by dense forest, which disappeared by times of its discovery.
