The variety of its landscapes is one of Luxembourg’s greatest attractions. The country is divided into two main regions : Oesling in the north and Guttland, comprising the Moselle valley in the east and the mineral basin in the south. Luxembourg counts 502,066 inhabitants, including 215,550 foreign residents representing 42.9% of the total population. LBBA is based in Luxembourg City only 5 minutes from the city center. The capital offers a striking contrast between the modern town perched on a rocky plateau with a sheer drop and the three old quarters of Grund, Clausen and Pfaffenthal. The quarter housing the European institutions has been located on the Kirchberg plateau to the northeast of the city since the 1960s.
