What an amazing old map of Washington, D.C. in 1851. I found this gem on the Library of Congress’ website. Click on it for a much larger version.

    It’s interesting how there is a grid but not that many houses in some parts so while it looks dense, it really isn’t. I guess that’s why they called it a “sleepy southern town” for such a long time. Where it’s not dense, but only a few houses per block my guess is the rest of the block is used for agriculture or animals.
    Also, how awesome would it be to see what the Washington Monument with the Potomac right up to it looked like.

    I like that the first longitude listed on this map is 0º 0′ 0″ — and then longitude relative to Greenwich.

    Today I learned more about the various prime meridians in Washington http://en.wikipedia.org/wiki/Washington_meridian And “Many western states have borders that are meridians of “longitude west of Washington”
