I don’t like any kind of hospital. But I strongly suggest you visit Hospital de la Santa Creu i Sant Pau (Hospital Sant Pau in short) when you travel to Barcelona.
It’s the oldest hospital in Spain. And the only hospital in this world which was declared as World Heritage by UNESCO for its singular architectural and artistic beauty.

There are several places where you can see the whole view of Barcelona. But I think you’d better choice Antoni Gaudi’s Guell Park.

If you only have time for one sightseeing in Barcelona, It must be Sagrada Familia (Expiatory Temple of the Holy Family). It’s where Antoni Gaudi and 5 generations best catalonia architects dedicated almost all of their life, These masters have worker for it more than 100 years, And still need many years to finish.
The ticket cost me 8 €. It’s the important outlay source for continue this large project. It’s worth.

Josep Ma. Subirachs was criticized for not complying with Gaudi’s original style. But he really culminated his work with these extraordinary set of sculptures for the Sagrada Familia.

There were five generation architects working for Sagrada Familia. All architects followed the idea of Antoni Gaudi’s mind.
Even in detail, Antoni Gaudi’s style is the most outstanding one.

I couldn’t express my heartquaking feeling when I standed at the feet of the Sagrada Familia. Everything seemed so insignificant in the presence of Antoni Gaudi’s unfinished masterpiece.
