Rising 512m and overlooking Barcelona, Tibidabo is the tallest mountain in the Serra de Collserola. Located on its summit is the beautiful church of Sagrat Cor (or the Expiatory Church of the Sacred Heart of Jesus), which is renowned for its statue of the sacred heart located below its highest tower and dominating the construction. It can even be seen from some of the districts in Barcelona. The most popular way to reach the church is via the cable car built in 1901. This mountain overlooking Barcelona is also home to the city's oldest amusement park. Some of the rides date back to the early 20th century!
