Here are the top 10 facts about Casa Batllo

Casa Batllo was renovated from an 1877 building

Casa Batllo was not a new building. 

It was an old building designed in 1877 by a man named Emilio Sala Cortes, who was also Antoni Gaudi’s teacher. 

When it was decided to demolish the old building, Gaudi stepped in with a bold idea to renovate it instead. 

This turned the old, boring building into a beautiful masterpiece of modern architecture, full of creativity and imagination.

Casa Batllo Features a Unique Natural Light Design

The interior of Casa Batllo is filled with light. 

This is because of smart design choices, which include a big skylight (a window on the roof) and two courtyards with blue shade from where light can come in.

Also, the tiles on the courtyards are darker at the top, and the windows get bigger as you go down the building. 

These ideas help spread light equally throughout the different floors.

Gaudi Designed an Innovative Ventilation System for Casa Batllo

Gaudi came up with a smart way to let fresh air into Casa Batllo. 

He created special openings on the windows that can be adjusted to let just the right amount of air inside. 

This ensured that people inside felt comfortable keeping the house cool in the summer and warm in the winter.

Casa Batllo’s Facade Is Decorated with Trencadis

Gaudi often used recycled materials in his work.

He used a technique called trencadís, which involved creating mosaics from broken glass and tile to decorate Casa Batllo’s front.

This eco-friendly and visually appealing technique became one of his signature design elements.

The Facade of Casa Batllo Has a Wavy Design

If you look closely at the front of Casa Batllo, you will notice that the walls have a pattern that looks like gentle waves in the sea. 

This and other decorative elements make the building look magical, especially in the morning and evening light.

Casa Batllo takes inspiration from the marine world

Gaudi was inspired by the sea when designing Casa Batllo. 

The glass windows on each floor will make you feel like you are underwater, gazing at the clear blue sea.

Gaudi was so inspired by nature that Casa Batllo often appears as a living organism. 

The wooden railing in the entrance hall looks like a huge sea creature’s backbone, and the attic’s curves make you feel like you are inside a whale.

Casa Batllo’s Balconies Are Uniquely Designed

The front balconies of Casa Batllo are not usual balconies. 

They have curvy railings made of iron shaped like a shell. 

These shapes appear different to people, with some saying that they look like masks, skulls, or even turtles.

Casa Batllo Is Known as “The House of the Dragon”

Casa Batllo is also known as “the House of the Dragon” because of its roof. 

The tiles on the roof look like the scales of a dragon’s back.
