Visiting Bartro House is an important reserved program for my Spanish trip. Here, gifted architect Gaudi applied the curve to the extreme. Guard-shaped roof chimneys, colored tiles and glass mosaics, ergonomic door and window handles and furniture, mushroom-shaped indoor flue design, shell spiral staircases and roofs, turtle-shaped glass skylights... Gaudi's imaginative performance makes the whole building seem to be full of vitality and amazes every visitor. Today, we have to rely on the sponsors on-site distribution of 3D equipment, in order to penetrate the screen of the machine, to discover those who are almost invisible to the naked eye, masterpieces!
