Old Durham Map
Here, courtesy of the Library of Congress, is a perspective map of Durham from 1891. The website is set up for viewing and navigation around the map in a pretty cool way, once you figure it out. It took me a while.
On the very left edge is a multi-storey building with a race track behind it. That's Trinity College, the small college that was later endowed by Benjamin Duke to become Duke University. There's a racetrack there becuase it was the fairgrounds before the college moved in.
It may be hard to find if you aren't familiar with the place, but right of center in downtown there is a short street labeled Roxboro Street. It only goes a few blocks north of the railway tracks and dead-ends. These days that street is a major artery and goes all the way to - well, Roxboro.
