This is a terrific old photograph of East Capitol St., before a street was even there. This was from the Library of Congress, and apparently was mislabeled as Baltimore’s Druid Hill Park. This too was taken by William M. Chase.

Don’t forget to compare this with the East Capitol shot we posted the other day.
Horatio Greenough’s statue indeed proves that this view is of the east U.S. Capitol grounds in Washington, DC, rather than of Baltimore’s Druid Hill Park. Here is a Wikipedia link for information about that statue;
