The Escaderiea Selaron is a work of art by the chilenian artist Jorge Selarón. He put over 2000 colorful tiles on the stairs in front of his house. As this took a lot of money people started to donate tiles from all over the world which he integrated into his work. https://en.wikipedia.org/wiki/Jorge_Selar%C3%B3n
Just in front of it is a mural depicting different artists that have had an impact on Lapa doing what the did in real live. Be it that they were musicians (on the left) or writers (middle) or painters (right) or even transvestites who had a lot of trouble with the police and then fighting them with capoeira.
