This paper analyzes the atmospheres of ambulatory pathways. Differences between promenade and seating, hardscape and nature, and new public art juxtaposed with residual industrial legacy, create opportunities for choice. A privileged view outward to the city can conflict with a protected simulation of a walk through a forested allée. What are the common features of design and the concerted resulting ambiance that distinguish the Promenade Plantée in Paris, Seoullo 7017 in Seoul and the High Line in New York How does renaturation and design by nature create urban islands of calm for people? The answers are in the complexity of interaction of the different design elements.
