Must see monuments

The Sagrada Familia is the world wide symbol of Barcelona. The monumental church El Temple Expiatori de la Sagrada Família (Expiatory Temple of the Sacred Family) is Gaudi's most famous work and the finest example of his visionary genius. The architect undertook the task in 1883 on the site of a previous neo-Gothic project begun in 1882 by F. del Villar. Gaudi dedicated his life to carrying out this ambitious undertaking which due to his sudden death was left unfinished. It ever since been in construction, as Gaudi's architectural project demands immense work. This Basilica is something else, its beauty is indescribable and the sensation when going inside it, although different for everyone, is marking for all.

Casa Batlló is one of the two great buildings designed by Antoni Gaudí on Passeig de Gràcia, the other being La Pedrera.
From the outside the façade of Casa Batlló looks like it has been made from skulls and bones. The "Skulls" are in fact balconies and the "bones" are supporting pillars.
Gaudí used colours and shapes found in marine life as inspiration for his creativity in this building. It's worth taking a visit to see Gaudí's Casa Batlló at night, when it is illuminated. 
This building is a stunningly original work and well worth the visit. If you decide to take a look around inside you will learn how much attention to detail Gaudí spent on his designs thinking about such things as varying window size depending on how high the window is from the top of the building. In this way he could ensure uniform lighting conditions in each room of the house. The audio tour that comes with the entrance ticket gives you fascinating insights into Gaudí and his influences when designing this house.

Casa Milà, popularly known as La Pedrera ('The Quarry'), is a modernist building in Barcelona, Catalonia, Spain. It was the last civil work designed by architect Antoni Gaudí, and was built from 1906 to 1912.
At the time, it was controversial because of the undulating stone facade and twisting wrought iron balconies and windows designed by Josep Maria Jujol. Structural innovations include a self-supporting stone front and columns, and floors free of load bearing walls. Also innovative is the underground garage.
It was declared a World Heritage Site by UNESCO. Currently, it is the headquarters of the Catalunya-La Pedrera Foundation, which manages the exhibitions, activities and public visits at Casa Mila.
