DESCRIPTION:We give a fresh view on Moebius geometry and show that the ide
 al boundary of a negatively curved space has a natural Moebius structure. 
 We discuss various cases of the interaction between the geometry of the sp
 ace and the Moebius geometry of its boundary.  We discuss an approach how 
 the concept of Moebius geometry can be generalized in order that it is use
 full for the boundaries of nonpositively curved spaces like higher rank sy
 mmetric spaces\, products of rank one spaces or cube complexes. In particu
 lar we describe a Moebius geometry on the Furstenberg boundary of a symmet
 ric space.
