The hospital was right next to the Grosse Pointe Park border, so either the eastern tower was on the hospital site, or the entire site was the hospital site and the trailer park site was where there's parkland... but that scenario doesn't make sense, so I'll go back to my first theory.

I do like these towers. But they seem a little out of place so alone along that stretch of the waterfront. They would fit in better along the Gold Coast near the Whittier. Or how about the pair, one on each side of the Belle Isle bridge approach [[one one Uniroyal, one on Richard Park)... sort of a pair of sentinels to the island....
