In "Invisible Cities," Italo Calvino explores the relationship between travelers and the cities they visit. Each new destination prompts a journey into the past, revealing aspects of one's identity that may have been forgotten or unrecognized. The experience of foreignness becomes a mirror reflecting what has changed within the traveler, highlighting the connection between personal history and the external landscapes they encounter.

This sense of rediscovery emphasizes how travel can evoke nostalgia and self-reflection. As individuals navigate unfamiliar environments, they often confront memories or emotions linked to their former selves. The cities become not just places to explore physically, but also arenas for introspection, where the traveler reconciles with their evolving identity amid the backdrop of the unknown.
