In the quiet forest of Grunewald, close to the Hundekehlesee, it's getting loud sometimes. The reason: Tennis club LTTC "Rot-Weiß" Berlin e.V. has its homebase here at the Steffi-Graf-Stadium. The German tennis legend lent her name for this location as she has been member of the club, together with "big names" such as Boris Becker, Sabine Lisicki or Gottfried von Cramm. The Steffi-Graf-Stadium offers 7.000 seats and is the venue for the Allianz Grand Champions and the Allianz Kundler German Juniors, one of the most important junior tennis cups in the world. On 16 clay courts and two hall courts, tennis pros play to win.
