The Casa Milà is one of the most famous works of the Catalan architect Antoni Gaudí.
It was designed between 1906 and 1912 as a residential building in Barcelona.
The building is also known as “La Pedrera,” which means “the stone quarry,” because of its rough and wavy stone façade.
Its design is very original, with curved lines, organic shapes, and no straight edges.
The balconies are made of wrought iron and have unique, abstract forms.
Inside, the building has open courtyards that bring natural light and fresh air into the apartments.
One of the most famous parts is the rooftop, where the chimneys look like sculptures or warriors.
In 1984, Casa Milà was declared a UNESCO World Heritage Site.
Today, it is open to visitors and is one of the most important landmarks of Barcelona.
