For around 40 years, the Centre sportif René Hartmann was maybe the most successful sports venue in Luxembourg, and the home of 2 of Luxembourg's most decorated sports club with T71 Dudelange and HB Dudelange! 18 championships were celebrated here and basketball teams like Real Madrid, CSKA Moscow, CF Barcelona and Mobilgirgi Varese showed off. Surely a GREAT chapter of Dudelange history !
