Blues'n Jazz Rallye in Grund/Clausen/Pfaffenthal
Blues'n Jazz Rallye is one of Luxembourg City's most popular open-air summer events, held across the UNESCO-listed districts of Grund, Clausen and Pfaffenthal. Six main sites, Neimënster, Melusina, Place Emile Mousel, Parc Mansfeld, Théiwesbuer and Sang a Klang, anchor the evening, while eight additional cafés and bistros along the route host their own free jazz and blues performances, letting visitors move between stages and terraces through the night.
Grund, Clausen and Pfaffenthal sit in the steep river valley beneath Luxembourg City's upper town, an area whose historic fortifications and dense, narrow streets earned it UNESCO World Heritage status.
