Barcelona is all about Antoni Gaudi, there are buildings, there is a church which is kinda famous and then there is Parc Guell.
Parc Guell is named after Esebi Guell, who was a Rich guy in Spain, so rich in fact that he decided that on a big old hill in Barcelona that he wanted a fancy garden, and when you want a fancy garden you get the fanciest of Architect Antoni Gaudi to design it for you.
It's still a private garden, now frequented by thousands of tourists everyday, as they climb the big old hill to see want Gaudi has designed. My included.
The answer is a winding path that takes you pass trees, and grottos, and mainly organic Gaudi like spaces. There is the house which Gaudi sort of lived in, and there are view across the whole of Barcelona.
There is a terrace which you have seen a thousand times, and there is almost that many tourists up there, below that is a columns which hold everything up, and that is a beautiful game of light
And as always there is beauty in the little details, the places away from the thousands of people, the things everyone walks past and no one cares about
and if you try very very hard, you can get a shot without people in it, but it's rare
