La Seu Cathedral
Bus #1 to centre; the cathedral is the seafront landmark
The golden Gothic hulk on the sea wall, its 13-metre rose window scattering confetti light across Gaudi's ironwork by morning. ~€10 entry against €150-a-couple ship tours that visit the same nave. Go before 11 for the light and the space.
Must try. The Parc de la Mar reflection pool photo from below
about $11
