San Vitale Basilica Labyrinth (Ravenna)

A circular marble labyrinth 3.4 meters in diameter, installed in the presbytery of San Vitale Basilica between 1538 and 1545 by Benedictine monks. The 7-circuit classical design in polychrome marble sits within one of the most important Byzantine buildings outside Constantinople — San Vitale's famous mosaics of Emperor Justinian and Empress Theodora date to 547 CE. The labyrinth's placement in the presbytery (near the altar, not the nave) suggests its use was restricted to clergy. At 319.22° Giza bearing, Ravenna — the last capital of the Western Roman Empire — sits on Adriatic coastal marshlands where fresh and salt water mix. The monks' decision to install a pagan-derived labyrinth 1,000 years after the basilica's construction reveals the enduring power of the archetype.
