Choose any year to see the closest dated map, source-identifiable structures active by that year, city-boundary changes, landscape events, and documented 1871 fire outcomes.
Explore each post-fire year through its annual map, construction and reconstruction projects, predecessor relationships, city-model notes, and the separate 1874 fire view.
Walk the town as the sources describe it, then switch on the confidence view: documented geometry renders solid, inferred is tinted, and anything we are guessing at turns to translucent massing. Click a building for its attributes and citations.
A research index, not invented certainty
The browsers distinguish individually identifiable buildings from anonymous permit and construction totals. Confidence flags, unresolved dates, source links, and explicit research gaps remain visible so the collection can improve without obscuring uncertainty.
