Editing Casa Batlló (section)

===Exterior façade===
[[File:CasaBatllo 0170.JPG|thumb|left|150px|The façade has three distinct sections.]]
The façade has three distinct sections which are harmoniously integrated. The lower ground floor with the main floor and two first-floor galleries are contained in a structure of [[Montjuïc]] sandstone with undulating lines. The central part, which reaches the last floor, is a multicolored section with protruding balconies. The top of the building is a crown, like a huge gable, which is at the same level as the roof and helps to conceal the room where there used to be water tanks. This room is currently empty. The top displays a [[Molding (decorative)|trim]] with ceramic pieces that has attracted multiple interpretations.

====Roof tile====

The roof's arched profile recalls the spine of a dragon with ceramic tiles for scales, and a small triangular window towards the right of the structure simulates the eye. Legend has it that it was once possible to see the [[Sagrada Família]] through this window, which was being built simultaneously. As of 2022, the partial view of the Sagrada Família is available from this vantage point, with its spires visible over newer buildings. The tiles were given a metallic sheen to simulate the varying scales of the monster, with the color grading from green on the right side, where the head begins, to deep blue and violet in the center, to red and pink on the left side of the building.

====Tower and bulb====
One of the highlights of the façade is a tower topped with a cross of four arms oriented to the cardinal directions. It is a bulbous, root-like structure that evokes plant life. There is a second bulb-shaped structure similarly reminiscent of a thalamus flower, which is represented by a cross with arms that are actually buds announcing the next flowering. The tower is decorated with monograms of Jesus (JHS), Maria (M with the ducal crown) and Joseph (JHP), made of ceramic pieces that stand out golden on the green background that covers the façade. These symbols show the deep religiosity of Gaudí, who was inspired by the contemporaneous construction of his basilica{{sfn|Bassegoda Nonell|1981}} to choose the theme of the holy family.

The bulb was broken when it was delivered, perhaps during transportation. Although the manufacturer committed to re-do the broken parts, Gaudí liked the aesthetic of the broken masonry and asked that the pieces be stuck to the main structure with lime mortar and held in with a brass ring.{{sfn|Bassegoda i Nonell|2001b|p=10}}

====Central section====
[[File:Casa Batllo.jpg|thumb|left|150px|The central part of the façade evokes the surface of a lake with water lilies.]]
The central part of the façade evokes the surface of a lake with water lilies, reminiscent of [[Claude Monet|Monet]]'s ''[[Water Lilies (Monet series)|Nymphéas]]'', with gentle ripples and reflections caused by the glass and ceramic mosaic.{{sfn|Bassegoda i Nonell|2001|p=75}} It is a great undulating surface covered with plaster fragments of colored glass discs combined with 330 rounds of polychrome pottery. The discs were designed by Gaudí and Jujol between tests during their stay in Majorca, while working on the restoration of the Cathedral of Palma.{{sfn|Bassegoda Nonell|1971}}

====Balcony====
Finally, above the central part of the façade is a smaller balcony, also iron, with a different exterior aesthetic, closer to a local type of lily. Two iron arms were installed here to support a pulley to raise and lower furniture.{{sfn|Lahuerta|2001|p=31}}

====Main floor====
The façade of the main floor, made entirely in sandstone, and is supported by two columns. The design is complemented by joinery windows set with multicolored stained glass.{{sfn|Bassegoda i Nonell|2001b|p=4}} In front of the large windows, as if they were pillars that support the complex stone structure, there are six fine columns that seem to simulate the bones of a limb, with an apparent central articulation; in fact, this is a floral decoration. The rounded shapes of the gaps and the lip-like edges carved into the stone surrounding them create a semblance of a fully open mouth, for which the Casa Batlló has been nicknamed the "house of yawns". The structure repeats on the first floor and in the design of two windows at the ends forming galleries, but on the large central window there are two balconies as described above.{{sfn|Bassegoda i Nonell|2001b|p=12}}
