10mm, clouds, Westfalenstadion The Signal Iduna Park - formerly known as Westfalenstadion - is home to Bundesliga-Club Borussia Dortmund and with a capacity of 83.000 visitors Germany's biggest football stadium. It was previously featured in this entry. I'm reasonably pleased how this B&W conversion turned out, the only thing that bothers me is the tree on the right which covers a part of this structure.Tomorrow I'll put up a color version that I prefer a bit to this one.
