The association was founded on 5 August 1934 as „Association sportive Catholique Ettelbruck“ (ACSE), 3 years after the first basketball section had been founded in Bettembourg (Luxembourg). The catholic youth federation was anxious to offer a sport, in order to be able to stand up to the competition of other youth organizations such as the Scouts or football federations. So basketball appeared to be a suitable sport. It is played in the „Lärchen“ on a meadow covered with a layer of ash.
