The stunning exterior, an equally stunning interior, and panoramic views honestly might leave you speechless. Located on the summit of Mount Tibidabo, Templo del Sagrado Corazon de Jesus ranks as the highest point in Barcelona. And, while you could spend hours admiring the architecture and artwork in and outside of this Romanesque church, travelers also recommend setting time aside to witness miles of Barcelonan landscapes from the top – a gorgeous view made even more impressive as the sun sets.
