ChicagoHenge, Manhattan Henge, etc
In many modern cities, the streets are lined up in a grid pattern (some are specifically N-S and E-W, and others are at different angle orientations). In those cities, you can have, for example, ChicagoHenge. That’s the day the sun lines up with our east-west streets. So you can get stunning pictures of the sunrise or sunset lined with skyscrapers.
