Secret tip: The Crypt of Gaudí in Colonia Guëll
Only 25 minutes away by train from Barcelona you will encounter Colonia Guëll. The industrial magnate moved his major textile factory to their and had a village built for his workers. He engaged several renown architects among them Gaudí to build a residential area with a lot of amenities that were very progressive for that time such as a permanent doctor.
When visiting the village you will come across magnificent modernism buildings: from residential houses to the unfinished church of Gaudī. Only the lower nave was finished after Guëll stopped financing the project in 1914 and Gaudí focused on his top project: La Sagrada Familia.
