Others have asserted it was there first on the basis of the aerial photograph of a building in the same location. But as I have linked Harriet Tubman school was clearly, 100% created on that spot in 1982. Now if that repurposed an old previously closed school building that’s possible but I haven’t found evidence of that. It’s pretty clear from what is written that Harriet Tubman was built there in 1980s in response to activism from the local black community wanting a school in their neighborhood.
