San Vitale basilica

The Basilica of San Vitale, contains a permanent floor labyrinth integrated into the 6th-century mosaic pavement. Located in the presbytery, this circular design features a single, winding path of marble tesserae leading toward a central point. While smaller in scale than the Gothic "walking" labyrinths, it functions as a meditative "prayer labyrinth." Its purpose was to facilitate spiritual growth by requiring the worshiper to trace the difficult path to the center visually or with a finger, symbolizing the soul’s journey through the complexities of the world toward salvation (link)
