Porta Palatina and the theatre make the Roman colony visible, but both survive through excavation, reconstruction and later urban clearance. The regular grid remains more extensive than the isolated monuments.
The cathedral and Shroud Chapel join worship, dynastic representation, fire damage and conservation. The Shroud’s identity belongs to religious tradition; consult the institution’s current information about its display.
The Quadrilatero contains homes, shops, worship and evening activity. A responsible route reads thresholds and reused fabric while leaving courtyards, services and resident movement unobstructed.
Begin at the Roman gate in quiet morning light, continue through the protected archaeological and cathedral areas, then cross the Quadrilatero without treating an inhabited district as a museum enclosure.
