Tibidabo (Catalan pronunciation: [tiβiˈðaβu]) is a hill overlooking Barcelona, Catalonia, Spain. At 512 metres (1,680 ft), it is the tallest hill in the Serra de Collserola. Rising sharply to the north-west, it has views over the city and the surrounding coastline.The summit of the hill is occupied by the Sagrat Cor church and adjacent Tibidabo Amusement Park. The Torre de Collserola telecommunications tower is a short walk away. All three are prominently visible from most of the city of Barcelona. Designed by Enric Sagnier, the church was started in 1902 and took 60 years to complete. It is topped by a sculpture of the Sacred Heart of Jesus by Josep Miret Llopart.
Tibidabo can be reached by road or via the Tibidabo Funicular, which was the first of its kind in Spain, and by the Tramvia Blau. Funicular operations recommenced in June 2021 after modernisation, however the tramway remains out of service. Replacement bus TC2 connects Tibidabo with Avinguda de Tibidabo Metro station. The Transports Metropolitans de Barcelona minibus service 111 connects it to Vallvidrera village and the upper station of the Vallvidrera funicular.
