Buderus Arena

Today I participated in a guided tour that took me to the Buderus Arena.
The Buderus Arena Wetzlar is a multifunctional arena in the Hessian city of Wetzlar. The event hall, which opened on March 11, 2005, has a maximum capacity of 6,000 spectators and an interior area of 2,468 m². (Wikipedia)
I won again via a competition in the daily newspaper.

It was very interesting and we were shown almost everything backstage. From changing rooms for sports teams, to changing rooms for artists, storage rooms, boxes, conference rooms, first-aid room, the room for operations management, direction, heating and emergency power supply. It took about an hour and a half and a lot of interesting details and funny anecdotes were told.
