Update: I did in fact back in July 2007; see the final four pictures of my first post for the neighborhood. I also returned to examine the two houses above in extensus in early March of 2020. I went back and looked at the west side of Benton Place in greater detail in January of 2021.
I could have sworn I’ve wandered down and photographed the first private street in St. Louis–some say the first in America–but apparently I haven’t. Designed by Julius Pitzman, in what would become dozens of privates streets in the area, this first design still holds up well.
