Esglesia de la Colonia Guell (Senior (65+))

Antoni Gaudí's work was started in 1908 but was never completed. In 2005, the underground chapel of the Domaine Güell was selected as a World Heritage Site. Even among Gaudí's many imaginative works, this underground chapel is considered to be a very unique one. The church looks like a cave, blending in with the surrounding trees. The unpolished stone columns are full of primitive mystery. Gaudí conducted a series of architectural experiments here, and the results were later applied to the Sagrada Familia.
