In the beginning it was called Calle de Nuestra Señora del Pópolo.
By mid 1876 Cartagena was struck by a terrible epidemic called "El Tablón", which is what we know today as a very strong flu. This epidemic killed many people in the city, there were houses where no one survived.
When the neighbors of San Diego neighborhood were going to burry the dead, they had to go by a certain street, and casually because of the state of the street two or three times those carrying the coffin would tumble and fall with the coffin.
Since 1876 each time someone wanted to give an address on this street they would say it was in the street where the dead fall (Tumbamuertos). Some neighbors even said it was a feasting elf who made the by passers fall.
