La Sagrada Familia is no doubt the most iconic structure in Barcelona. The church, located in L'Eixample, has been a fixture in Barcelona since construction commenced in 1882 and as building continues on today the structure's fame only grows.
Though still a work in progress, the church already is an amazingly intricate structure. Antoni Gaudí spent 43 years on this project and, since his death in 1926, the duty to finish it has been passed on to several architects. Though the responsibility continues to change hands over the years, the architects have all respected Gaudí's vision and have made additions with his design in mind.
Inside the church has an impressive stained glass windows line the main room and a lift takes visitors up one of the towers to enjoy the view. Smaller rooms hold exhibits detailing the history and future of the structure. La Sagrada Familia is projected to be completed in 2026, the 100th anniversary of Gaudí.
