A site which I’m often on http://www.worldstadiums.com/ Not everyone’s favourite, but it really interests me. I plan to start designing them using AutoCAD software.
Hopefully, in the future we stop designing stadiums like this.

And start to design and build stadiums more like this
Baku Olympic Stadium in Baku, Azerbaijan (+65,000)
