Slideshow: Olympiastadion - Munich, Germany

Unfortunately the lighting in these photos isn't great and the overcast sky washed out the backgrounds, but they still offer an up close view of a stunning piece of architecture. Still impressive after 30 years, the Munich Olympic Stadium steals the thunder from the newer flashier design of the BMW World by Coop Himmelb(l)au, across the street. These flowing tent like structures decked out with glass roofs are magnificent to behold, an expression of structure that captivates the imagination and boggles the mind. It's amazing the calculations and design challenges overcame in this project long before digital design tools were the norm for architectural practices.
