Xenon of Saint Catherine

The Xenon of Saint Catherine is a fascinating stop if you're into history and medieval architecture — it's one of Rhodes' lesser-known gems that doubles as an exhibition space showcasing artifacts and art tied to the island's rich past. The atmosphere is quietly impressive, with collections that span archaeological finds from Rhodes and the surrounding islands alongside works from notable Greek artists. It's the kind of place that gives you real context for everything you're seeing out in the streets of the Old Town.
