If you'd like a video I can endorse, here's a good Tim Traveler video about the largest stadium in the world (now abandoned). Things of interest here:
1. I am entirely captivated by the abandoned piano at 2:35, evolved into a sort of permanent planter like the art car that lives in Toronto's Kensington Market

2. The British pronunciation of "Funicular"
3. I am now very curious to see someone do a history of athletic self-improvement orgs being oppressed by governments
