I'm currently writing a fantasy story, but i need a good setting. Specifically a structure, like a bridge, a tower, etc. The requirements are here: 1. Tall. Can be the tip of the structure or like an arch. Ex: Arch of the Golden Gate bridge. 2. The tall points have to be wide enough for two average people to walk on easily without falling. 3. There must be multiple tall points. 4. Tall points cannot be too apart. Ex: Golden Gate Bridge, too far. 5. Must have many beams and ropes intersecting so you can get to the top just by swinging and jumping. Ex: Eiffel tower. 6. Overlooking a port/sea/ river, etc. As you can see of my constant use of the Golden Gate Bridge, I've thought of using it, but it wasn't perfect. Please help me if you know a structure that fits this description. I need to use it for a story I am writing and the location is very important.
