When Barcelona grew in the 19th century, the old city walls were demolished and the city began to expand. The people of Barcelona
took the opportunity and said "Out with the old - In with the new". In this case, a new style of architecture called Modernism
was implemented. One of the interesting results of the time came from the famous Catalan architect Antoni Gaudi. This house - the
"Casa Batllo" or simply "The Gaudi House" - is located at the Pg. de Gracia. It's well worth the wait until the lights start to bring
the walls to life!
