Progressive Era city maps
These maps share a historical moment, not a coastline or state line. Read them together and the period starts to show its habits of building, trade, and self-presentation.
Reading Note
Progressive Era grows sharper once the cities line up
Baltimore 1912 and Boston 1905 sit in the same historical slice even when they stand in different regions. Read together, the pages show how one period pressed cities toward similar acts of self-presentation.
Coastal Cities and Harbor Cities keep returning in this group, which is why terminals, harbor edges, new grids, and engineered ground move into the foreground when you browse by era.
