From The New Yorker slideshow "Mapping Mannahatta"
An interesting comparison from the Castello Plan and the modern OpenStreetMap of points I chose to correspond to both the 21st century and the 17th century depiction which shows that the old streets are close to where they once were, the distortion may be do to the later flattening of “the island of hills”. (MapAnalyst listing in IdeARK translated)
The original Castello Plan ("Image of the city Amsterdam in New Nederland") notice the wall later, Wall Street:
If you look close you could take the map and using Google SketchUp 7 actually “loft” most of these buildings as they are quite 3D for the time. Interesting map. I have a theory that economic recession brought land-filling to the shores which created the island as it is today. The last one created the WTC and Battery Park City which were almost at the bottom to the right of the “wall” where the English doing business had a warehouse in the middle of the ironmongers and the first ferry to Brooklyn. The “Water Gate” at the wall and East River (here on the bottom Hudson River on the top) was closed at dusk and opened at dawn.
