Visiting to a cemetery may not be your first thought when exploring a new city, but the Montjuïc Cemetery, makes for a bizarre, yet fascinating experience. Located on the side of Montjuïc Hill, it was created in 1883 and is like a mini city, showcasing the change of time. Choose to follow the historic or the artistic route, taking in graves of famous Catalans such as as the the architect Ildefons Cerdà, the artist Joan Miró and FC Barcelona founder Joan Gamper. It's also a great place for views - I love coming up here to look over the city.
