Yeah, it's really hard to tell how steep MC is until you're there. It's built in vertical tiers.
Have you ever played Mass Effect? Monaco (Monte-Carlo, in particular) is like a real life version of the Citadel presidium. This odd mix of green space and technology. There are public elevators and escalators built into the landscape. And they're immaculately clean, even though they're in the open air. Everything is terraced, everything is open, roofs are flat and often serve as things like small parks. The top of the huge seawall at the entrance to Port Hercule is also a park. You can walk directly into the Monaco Yacht Club without any kind of gate or restriction. It's just... open. There are terraced walkways that just suddenly end, overlooking the water or the street below. It's kind of a maze, a beautiful one.
