Atlante San Alejo Wikipedia
Atlante played in San Alejo, La Unión. The club was previously called Guardia Nacional however in the 1955–1956 season they changed their name to AD Atlante after they won promotion to the country's top tier. The club team name derived because of the location's nearby shore, although, La Unión is a port city on the Pacific Ocean, not the Atlantic Ocean.
Atlante never won a national title in El Salvador. However, they did manage to finish second in the 1956–1957 national regular season league, and runners-up again in 1962. In 1970 they relegated to the second division. Ranchero Guerra (1962)
