MITREOISIDE — Mithraeum Contemporary Art
MITREOISIDE is an unusual cultural space that combines access to an ancient Roman mithraeum — a subterranean sanctuary dedicated to the mystery cult of Mithras — with a programme of contemporary art exhibitions and interventions. Located in the greater Rome area, the site invites artists to respond to the charged atmosphere of an underground Roman religious space, creating a dialogue between the ritual architecture of the 2nd–3rd century CE and contemporary visual practice. The resulting encounters between ancient stone and current artistic language have made MITREOISIDE a distinctive point on Rome’s independent cultural circuit.

Overview
Mithraea are among the most evocative survivals of Roman religious life: narrow underground halls lit by torches, lined with stone benches for initiates, and typically decorated with painted scenes of the god Mithras slaying a sacred bull (the tauroctony). More than 400 mithraea have been identified across the Roman Empire, with a notable concentration in Rome and its port city Ostia Antica. MITREOISIDE uses one such space as a living cultural laboratory, hosting artists whose work enters into conversation with Roman sacred geometry, myth, and the phenomenology of underground space.
History
The cult of Mithras spread through the Roman Empire from the 1st century CE onwards, finding particular favour among soldiers, merchants, and imperial freedmen. Mithraea were deliberately built below street level or carved into hillsides to evoke the cave in which Mithras was said to have slain the bull and released the life force of the cosmos. The cult was suppressed with the Christianisation of the empire in the late 4th century; most mithraea were sealed, demolished, or converted into Christian chapels.
The site now known as MITREOISIDE was rediscovered through archaeological investigation and subsequently activated as a cultural venue, following a broader Italian tradition of using ancient underground spaces for contemporary arts programming. The project brings together archaeologists, curators, and artists to maintain the site while generating new creative work.
What you see
The mithraeum is a low, barrel-vaulted chamber carved or built below ground level, with stone podia (benches) running along both long walls where initiates reclined during ritual meals. The central aisle, lit today by artificial lighting, would originally have accommodated the altar with the tauroctony relief. Contemporary artworks installed by invited artists occupy the space with a minimum of intervention, typically favouring light, sound, and site-specific sculpture that respects the integrity of the ancient structure.
Cultural significance
MITREOISIDE exemplifies a model of heritage activation gaining traction in Italy: instead of treating ancient spaces purely as archaeological museums, the site invites contemporary culture to inhabit them, sustaining public interest and funding conservation through artistic use. The dialogue between Roman mystery religion and 21st-century visual art makes the space a thought-provoking destination for both heritage visitors and contemporary art audiences. Cultural Heritage Online documents it as a crossover between archaeological heritage and live culture in the Rome area.
