Okay, picture this: 18th century Barcelona, a man of legend slipping through these narrow streets, leaving a trail of scandal and seduction. That's Casanova. We're walking through Born, the neighborhood where his story becomes real and messy, unforgettable in its chaos. You'll stand where he stood. These stone walls rise around you, centuries old and solid. We're hitting Palau Moja, where power and passion collided, then Portal del Born, where the city's heartbeat still echoes. Finally, Basílica de Santa Maria del Mar, this soaring medieval church with ribbed vaults and light pouring through stained glass, where the acoustics carry sound in unexpected ways. Twenty-one minutes total. Easy pace. No climbing. Just you, me, and a man who knew how to disappear. Ready to chase a ghost?
