“The restoration work on the stained glass windows of the Casa Batlló on the main façade.by Antoni GaudíThe main focus of the project was the recovery of the network of cibas of the original work. On this façade Gaudí worked with the Amigó workshop, one of the most important of the time. After successive restorations the stained glass windows had lost part of their blown pieces and had been replaced by printed glass, much more modern and discordant in appearance with the whole. Gaudí uses cibas blown and slightly wavy. This intervention required the plumbing of some panels. The House Batlló together with the Sagrada Família one of the most visited buildings in Barcelona.” Wikipedia
