A detail of a city-wide map showing the approximate limits of the historical centre of Milan. I’m guessing that this is located in or near the Duomo Metro station, based on the way that the map is worn away at that point – as I’ve mentioned before, many users will actually point to their starting location on a map as they trace their intended route.

The thick green/yellow/red lines are the Metro, blue lines are the tram and brown/maroon lines would be buses. Numbers in circles show route termini; numbers in squares allow you to follow a route from point to point.

The area shown here is actually easily walkable without the use of public transport, unless you’re in a hurry, I guess!
