San Salvador is connected by rail with Santa Ana on the north-west and with the Pacific ports of La Libertad and Acajutla.
It was founded in 1527 by Juan de Ampues, who gave to it the name of Santa Ana de Coriana (afterwards corrupted to Santa Ana de Coro) in honour of the day and of the tribe of Indians inhabiting this locality.
