The incredible private house of Manuel Vicens i Montaner, crafted by the renowned architect Gaudí when he was only 30 years old, is a Unesco-listed masterpiece tucked away in the west of Gràcia. The lavish facade is decorated with ceramics of brilliant colors and textures, topped by striking marigold tiling. The house was opened to the public in 2017 and visitors are welcome to explore on their own or take part in a one-hour guided tour (available in Catalan, Spanish, English and French) to really experience the beauty of the structure.
