Parc Güell
If you liked the Sagrada Família, you may also like Parc Güell, a park complex also designed by Antoni Gaudí.
Parc Güell was origionally designed to be a housing "park" for the rich, but today is open to the public.
The two entrance buildings are like ginger bread houses and the mosaic serpent/dragon is a fountain that takes water from the main terrace above.
It's a steep climb up to Parc Güell, which is why the street has an escalator, but the reward is peace, quiet and fresh air.
