Castel Sant'Angelo, a magnificent structure originally built as Emperor Hadrian's mausoleum and transformed over centuries into a fortress, a papal residence, and now, a museum. The ancient stones here have seen it all, from fierce battles to artistic triumphs.

Start your exploration in the lower chambers, where the history of ancient Rome is etched into the walls. Climb the winding staircases to discover intricately decorated halls, secret passageways, and the stunning Sala Paolina, adorned with frescoes that tell stories of power and devotion.
