The Armed Forces Officers Club in Abu Dhabi has 120,000 square meter roof constructed from a 3 large concrete shells. My first thought was that it looked a lot like the Olympic Stadium in Montreal so it’s no surprise that both were designed by Roger Taillibert, a French architect who clearly thinks he’s designing spacecraft rather than buildings. There’s ground level photos and design sketches on Tallibert’s website.

Home of the Oregon Ducks American Football team is Autzen Stadium in Eugene, Oregon. The central “O” and end-zone “Oregon” is clearly visible in signature yellow on green.

Stadion Dziesięciolecia (Polish for 10th Anniversary Stadium) is the biggest stadium in Warsaw but was abandoned in 1983. It is now home to the Jarmark Europa market, which runs every weekend. In the satellite photo you can see the stalls of over 5,000 companies (More info).
