Ten blocks to the east may be seen the U.S. Capitol where Ingersoll argued cases before the U.S. Supreme Court in 1875 and 1876. (The Supreme Court sat in the Old Senate Chamber.)
Ingersoll was what was known as a “parliamentary lawyer” and as such he lobbied on Capitol Hill and appeared before administrative agencies. He was so often present on the floors of Congress that he was taken to be a member or former member.
Walking Directions (printable version)
To walk to tour stop #7:
Go west (away from the Capitol) five blocks on Pennsylvania Avenue to Freedom Plaza. Freedom Plaza is a white marble platform that constitutes a public space between E Street and Pennsylvania Avenue, N.W., and between 13th and 14th Streets, N.W. From here you can see the U.S. Capitol to the east, and the National Theater — stop #7 — to the North.
