This is a relatively new place to climb in Bremen, it is situated within the Sportgarten E.V. which is located to the rear of the Werder Bremen football stadium.
It is an artificial wall constructed from some sort of concrete, and has various types of grips and holds crafted into it.
You can lead (bolted sport) or top rope and there are great opportunities for boldering around the whole thing. the routes vary in hardness and i have been told they are now marked on to the wall along with their grade.
A good fun place for a climb, and if you get bored there are a few halfpipes close by.
