The main entrance to Park Güell is on the south side, on Carrer d’Olot, from which visitors can enjoy the spectacular view of the stairway with the hypostyle room. The wall of the park is made of rustic stone topped with ceramic tiling and medallions bearing the name of Park Güell. The iron gates, designed in the shape of palm leaves, do not form part of the original plan, but came from Casa Vicens. To either side are the two pavilions that form the porter’s lodge. The one to the left was the one actually used as a porter’s lodge, with a waiting room and telephone booth, while the one to the right was the porter’s residence, whence the name Casa del Guarda, though it is today part of the Barcelona History Museum. Both have very beautiful roofs, built with the traditional Catalan clay tiles covered with “trencadís”, a mosaic made of tile shards.
