Timisoara, Romania. The city has quite a few city models, some for current navigation
The only hint of where you are is the worn spot. Like any map without that reference, "you are here" because that's where other people think they are, and touch it.
Models are used for historical aspects of the city, as well as paving color and plaques to indicate buried foundations. Unfortunately they use the same rust red color for decorative paving patterns, around the city.
