They supposedly called this the "Gate of Death". It was built in 1916 by Peter Kern. He founded the neighborhood and I lived in his house at the top of Cincinnati Street. Apparently he was connected with some very odd Illuminati and Masonic types and lots of mystery surrounds it. I can attest that it was a very strange place to grow up. Very quiet. Too quiet. In retrospect, I think I grew up surrounded by Satan worshippers. I did not know that at that time. They say Peter Kern was decapitated in a ritual sacrifice underneath that sign. It was torn down in the 1950s and I moved there in 1973 or so.
