A collection of maps of Pittsburgh on the occasion of that city’s 250th anniversary. “This selection of maps and views presents a history of the city and region from [1758] to near the present; some can be seen on other pages of this website. There are few earlier large scale maps of the region because there was nothing there of interest. The earliest regional map appears to be the manuscript Mercer’s Map (#1753.1) and there are a few manuscript maps of Fort Duquesne built 1754-55, see the 1750s pages for the existing maps.” Via MapHist and Map the Universe.
