I had three hours in Rome, patchy data, and a loose mental list of monuments to see before reaching Termini station. Navigation apps know where to go, guidebooks know what you’re looking at, but nothing does both. After trying Google My Maps, Apple Maps, and HTML exports, I found the solution in Obsidian’s Leaflet plugin: one note with an interactive map, route overlay, historical context for each stop, and direct links to Google Maps for turn-by-turn navigation between waypoints.
