The modern city was born in 1887 when the Santa Fe Railroad built a connector line between San Bernardino and Pasadena, prompting the Semi-Tropic Land and Water Company to found town sites every mile and a half . A Methodist colony from Kansas purchased the land and named their new home after the Rialto Bridge in Venice .
