Most people don’t really realise that the city of Los Angeles - ‘the city of angels’ - in fact has a much longer name. Originally, the ful name was “El Pueblo de la Reina de los Angeles,” which translates as “The Town of the Queen of the Angels.”
This name was given by the Spanish settlers who established the pueblo in 1781 near a river they named Río de Porciúncula, after the small chapel of the same name in Assisi, Italy - it was named by Franciscan missionaries travelling to explore California and that was where their order was founded.
