Berkley School aka Hosanna School
From the Historic Hosanna School Museum website:
The building of these schools was mandated by law across all of the former slave-holding states for the purpose of educating the recently freed African Americans.
The property upon which Hosanna stands was first owned by a free African American man named Cupid Paca. In 1822 Paca bought fifty acres of land running from Berkley into Darlington. When he died, his holdings were divided among his surviving children.
