Parc Güell

Parc Güell is most known attraction of Barcelona, the Wikipedia
has very good description and links to that. Okay, let's see Dragon, Gaudi's house, great termitary and beautiful ceiling; let's do some megabytes of photos with tourists and fragments of Antonio Gaudi's opus magnum. And then?
Then sit down and enjoy surprising calmness, views to the sea and city, people playing ball,
watch incredible colors of mosaics in soft, mediterranean light. Opus magnum, indeed.
