In London's Shard, the gent's toilets of the observation deck (on approx the 70th floor) have glass walls behind the urinals so if you look straight ahead while using them it is as if you are peeing on the city of London from a great height.
The old Warner stand at Lord's cricket ground used to be where the press watched from (before the new Media Centre was built). The urinals in old stand used to have windows above them looking out over the pitch so that the journalists wouldn't miss anything whilst they urinated.
I always enjoy a "loo with a view", including that one at the Shard. I also enjoyed the outdoor one I utilized in Botswana that had the toilet isolated from camp behind a small wooden fence, but while sitting on the throne you are facing out from a slight elevation onto a sweeping 180 degree view of the savanna, with antelopes, giraffes, and elephants roaming around.
"Back in my day," Lake Helen (~10,000 ft) on Mt. Shasta had a pit toilet without walls that faced the valley. Depending on the weather, it could even be above the clouds/fog and IIRC on a clear day you could see the ocean.
I've been on something similar in Washington State. Forget where. Maybe below Shuksan someplace. While wilderness experiences are obviously a different matter, I suspect that people here freaking out about lack of doors or whatever wouldn't necessarily be comfortable with how many deal with climbing/camping/canoeing/etc. People just look the other way.
At a road stop somewhere at 5000 meters on a mountain somewhere in Sichuan (a day out of Chengdu?), the latrine was two slippery 2-by-4s over an open pit. I’m really glad I just had to pee, because that was terrifying.
The W in Santiago, Chile, has a full-length floor-to-ceiling glass window in the shower, with the morning sun shining right in. Your other option is a bathtub set in the middle of the bedroom itself. Mercifully the WC has a door.
Pretty sure I went to a bar in NYC that still had a urinal trough running directly below the bar as you were standing there... so one wouldn't need to leave the bar to take a leak. This was 30 years ago. McSorleys maybe?
