Irish Hill, located on what is today know as the Dog Patch neighboorhood of S.F., was an area comprised of mostly boarding houses where immigrants who worked at the nearby Pacific Rolling Mill lived.
"In the early 1880’s it was mostly all hotels on Irish Hill. You went up on Irish Hill when you got off work and you never left it until morning. The boys from one hotel would challenge the boys from another hotel and fight all Saturday afternoon in a hayrope ring outside Gately’s Hotel. Then we’d all go in and knock off steam beers for a nickel a piece…"
-Sheriff’s deputy Billy Carr
The remnants of Irish Hill can still be seen near the corner of 22nd and Illinois.
