This is the AT&T main telephone exchange in Houston, Texas.. (look at the car park at the bottom to get an idea of its size..)
This is a local telephone exchange in Suffolk, England (I was cycling past it and wondered “why put a shed in the middle of nowhere?” and thought I would investigate :groucho:)
everyone at suffolk must still use letters,or pidgeons, to communicate cos this is, just newbury and the surrounding areas exchange
couldnt find any other piccy sorry, but its the one dominating the landscape on the right, and its a huggge piece of junk and concrete, they were thinking of pulling it down, cos i have a feeling it doesnt really get worked anymore
