Halfway between Montserrat and Barcelona, we take a side road along the Llobregat River until we reach the old industrial textile colony of Santa Coloma de Cervelló. The whole village is like a live museum from the 19th century Industrial Revolution. The inhabitants still live in the old factory workers’ homes. The theater, the teacher’s house and the convent where children and the sick were cared, are still in good condition. A short walk will lead you to the most fascinating building: the Güell Crypt designed by Antoni Gaudí (1909-1915), declared a UNESCO World Heritage Site. It is really worth the trip to admire one of Gaudí’s last architectural works. The visitor center offers a superb display focused on two different subjects: The ground floor is about the process of the former textile industry, and the upper floor houses a single-room exhibition about Gaudí’s technology and the symbolism of his ceramic designs.
