A very nice building south of the Barrio de El Raval in Barcelona city. A architectural jewel in Barcelona. Unquestionably it is of compulsory visit. Not many tourists have knowledge of this place. But it deserves a lot of value.It also has a lot of history in each corner since it was raised between 879 and 911. Even though it was then reformed in the 13th century to give it its Roman style that can be appreciated today.
