An earlier general store on this corner is burgled in 1741, sparking the panic of the supposed "Great Negro Plot"
Long before the tower, a general store belonged to Robert and Rebecca Hogg at the corner of Broad and what is now South William Street. A burglary there on February 28, 1741 set off a panic, and officials treated it as one piece of a supposed "Great Negro Plot" to burn the town. By the time the hysteria ended, 34 people, mostly enslaved Africans, had been hanged or burned at the stake.

Ephemeral New York, drawing on New York Songlines, explains that the picture shows Commerce linking the two hemispheres through electricity. The blog praised it as a lovely dome in a 2012 post, so it was still there more than eight decades later.
