Hello friend, The old part of Barcelona is for me the cradle of architecture, since it has incredible facades of many years that contains a lot of history and culture, together with its beautiful vegetation form a great landscape to enjoy, the great works of Gaudi. The Palau Sant Jordi, I think it is very visionary but at the same time it does not have any similarity to the architecture of Gaudi, it will be because of the habit of seeing his works so full of life, but as for all there are different tastes, I am still betting on the work of Gaudi, and only in the concerts gives a lot of life to the Palau Sant Jordi, greetings and I really liked your publication and learned something new @oldtimer
