Palau De La Musica: The Concert Hall of Barcelona’s Palau de la Música Catalana is a magical space, conceived and designed as an enormous glass box crowned with a large central skylight. Listed as a UNESCO World Heritage Site since 1997, the Palau de la Música Catalana ("Palace of Catalan Music") was built between 1905 and 1908. Catalan architect Lluís Domènech i Montaner designed the building, which was primarily funded by donations from the city’s bourgeoisie. The theatre's patrons encouraged Montaner to build a uniquely Catalan building to express their Nationalist sympathies. The architect engaged local craftsmen and artisans, who created the vivid ornamentation and sculpture which decorates the entire building.
La Sagrada familia:La Sagrada Familia is one of Gaudi's most famous works in Barcelona. It's a giant temple that has been under construction since 1882 and it's not expected to be completed for between 30 to 80 years Much controversy surrounds the building of the Sagrada Familia. Today new construction materials are being used which, some feel, Gaudi himself would not have used.
Torre de collserola:Torre de Collserola is a uniquely designed tower located on the Tibidabo hill in the Serra de Collserola, in Barcelona, Catalonia, Spain. It was designed by architect Sir Norman Foster, and built in 1991 for the 1992 Summer Olympics. It features a pod for floor space like many towers but uses guy wires for lateral support like a mast. Mainly used as a TV and radio transmitter, this futuristic design provides the highest viewpoint over the city. The top antenna reaches 288.4m (946 ft) and the top of the pod, which has thirteen floors, reaches 152m (499 ft).
Tibidabo:is a mountain overlooking Barcelona, Catalonia, Spain. At 512 meters it is the tallest mountain in the Serra de Collserola. Rising sharply to the north-west, it affords spectacular views over the city and the surrounding coastline.
There is an amusement park, a telecommunications tower (Torre de Collserola), and a Catholic church, the Temple de Sagrat Cor, at the top, all of which are visible from most of the city. Designed by Enric Sagnier, the church took 60 years to construct and is topped by a sculpture of the Sacred Heart by Josep Miret Llopart. The Amusement park is the oldest in Barcelona and retains most of the original rides, some of which date to the turn of the 20th century. The park features in the Woody Allen film Vicky Cristina Barcelona.
