About a year ago I posted a photograph from the 1970s of the main parking lot at the Naval Hospital in Taipei.
Victor recently sent me these images of the hospital that he believes are from around 1979, shortly after the U.S. withdrawal. In the first one he circled the hospital complex itself (to the right, in green).
In the second, he circled in red the hospital parking lot that was shown in my post from last year. Just below that is the baseball field, circled in blue. The large yellow square encloses the Veterans General Hospital complex.
You can see what that area looks like today on Google Maps. Just click on this link and you'll find that some tennis courts and parts of some buildings are approximately where the hospital parking lot used to be. You can also use Street View to see the neighborhood at street level. The tennis court fences are on the right side and are covered so you can't see the courts themselves.
Like most everything else in Taipei, very little looks as it did when I was there.
