SearchResearch Challenge (10/26/22): A missing building in the park?

 Blank spaces on maps intrigue me, 

What was once here? 

.. as do blank spaces on the land.  More than a few SRS Challenges have centered on attempting to find out what happened here--this week's is in that category--what happened here? 

In this case, I was walking through a local park and happened upon an area (see the image above) at 37.885832, -122.261408 that was fairly blank.  Since it was on an otherwise hilly area, it looked very much as if a building had been there at one time.  There were a few pieces of flat concrete that looked suspiciously like former building foundations, and even more mysteriously, there's a flagpole on the western edge of the flat spot.  

Well... huh.  What's up? After a bit of SRS I found the answer AND another interesting story about the place. This leads to today's Challenges: 

1. What was once at 37.885832, -122.261408?  Can you figure out the story given just that lat/long and a keen desire to figure out the past?  Was there a building there?  If so, who built it and why?

2. The architect that that building is also the architect of a few other pieces nearby.  Can you figure one that's closest to this spot?  

As I mentioned last time, I'm deep in the middle of running my class at Stanford, so I'm going to keep the SRS Challenges on the interesting/fun but not-difficult side for the next 2 months.  Hope you enjoy these just as much!
