The Sagrada Família church, one of Barcelona's most famous landmarks, has never even been completed. The massive church has been under construction since 1882 and is still years from being finished. The church's architect, Antoni Gaudí, designed many buildings throughout Barcelona, and is responsible for Park Güell, a beautiful place I'll discuss in my next post.
My tour guide discusses the Arc de Triomf, built for the 1888 Universal Exhibition. This is part of a great bike tour of Barcelona I took that showed me all around the city. There was even a stop in a park for some sangria!
