3 must-see hop-off attractionsOk, you can only see three things in Barcelona? Well, if we had to choose, we’d say get in one of our open-top buses and begin by hopping off at Barri Gòtic, the old Gothic Quarter, the centre of the old city. This medieval maze of narrow streets and shady plazas is full of interesting buildings and places to sit and enjoy a coffee. It’s been the centre of the city since the Romans were here and you can still evidence of Roman life here beneath the Gothic Quarter’s Plaça del Rei. Barcelona is the city of Gaudí and our next two recommendations both have Gaudí in common. Hop off at the Sagrada Familia to see one of the most astonishing buildings in the world, the product of an incredibly fertile imagination running riot. Still unfinished after more than 130 years, the Sagrada Familia is one place you just cannot visit Barcelona without seeing. The last stop is Park Güell, another incredible Gaudí creation. Originally conceived as a housing development, it’s now a park which enjoys spectacular views over the city.
