Palau Güell

Built between 1886 and 1890 as the primary urban residence of industrialist Eusebi Güell just off Las Ramblas, establishing Gaudí's reputation among Barcelona's high-society cultural elite.

Monumental central salon rising 17 meters into a parabolic dome perforated with celestial apertures that filter daylight like stars. The rooftop showcases 20 sculptural chimneys encrusted with multicolored ceramic trencadís and glass.

Urban legends suggested subterranean tunnels linked the mansion directly to the royal port docks for secret escapes, whereas the basement was actually an ingenious stable and ventilation vault.
