Dirty Harry - Park Emergency Hospital
Then … The deep knife wound inflicted by Callahan at the Mount Davidson Cross forces Scorpio to seek treatment. He limps into the small emergency hospital at 811 Stanyan Street close to Kezar Stadium at the southeast corner of Golden Gate Park (map).
… and Now, the building, a designated City Landmark, was built in 1902, one of four emergency hospitals in San Francisco during the early 1900s. It continued in this capacity until 1978 then as an ambulance station until 1991. It now serves as offices for the city’s Recreation and Parks District.
Its original name is still engraved in the stonework above the entrance.
The doctor who treated Scorpio calls the police to report the unusual situation. Inside the hospital Callahan desperately wants to know if he recognized the patient - Scorpio’s buried victim Ann Mary Deacon only has one hour of oxygen remaining.
Then … The doctor does indeed remember him. He takes Callahan outside the rear of the building and beckons across the parking lot to Kezar Stadium … apparently the man occasionally works for the groundskeeper who lets him stay in a room there.
… and Now, this aerial shows the matching buildings relative to the hospital. In the movie image above, the stadium stands are behind and to the left of the “NO THRU TRAFFIC’ sign; that structure was demolished in 1989 when the stadium was downsized to its current configuration. The other buildings visible above, circled in yellow below, are still there.
