Mithraea are ancient underground temples dedicated to the worship of Mithras, a deity associated with the sun and light in Roman mythology. These structures were primarily built during the 1st to 4th centuries CE, often located beneath buildings in urban areas. The temples typically feature a central altar and niches for statues, where rituals and ceremonies were conducted by followers. The design of a Mithraeum often reflects the themes of rebirth and salvation, with many depicting the iconic scene of Mithras slaying a bull, known as the "tauroctony." This imagery symbolizes the cycle of life and the promise of eternal life for devotees.
