About two weeks ago, I was in Mannheim Germany and noticed that the side of this building was just like a mirror with a red frame.
Since I've joined the 365 challenge, I don't leave the house without my "good" camera anymore :-) and took these pictures on my way to an appointment in the building just to the left.
The building with the red frame was built in 2008 and belongs to the National Theater in Mannheim. It is a warehouse/workshop for the stages and scenery of the National Theater. It houses all of the stage props as well as the machinery and equipment to make the scenery for the operas and theater productions.
In the reflection of the windows of the Werkhaus, from one angle you see the modern (1974) high-rise apartment building called Collini Center and from another angle you see a historic (1904) building which is now a hotel.
Since Mannheim was almost completely destroyed in WWII, there are very few historic buildings still standing and this one is now a hotel with historic landmark status for it's art nouveau facade.
If you look closely you can see the machinery of the theater workshop behind the windows.
