Centre D'Esports L'Hospitalet was founded in 1957, through of merger of the three teams from the city: UD Hospitalet, CD Santa Eulalia and CF Hércules.
It managed to appear three times in Segunda División, but this was prior to the creation of Segunda División B as the new third level, a category the club first reached in 1982 and where it would remain for the vast majority of the following two decades.
