Jefferson Davis Hospital
From Deadhaus
ST Note: While I've taken creative liberties with its floorplan, the Jefferson Davis hospital is a real place. Or at least it was... It's currently being used as artists' lofts in our world.
By the way, it really is built on top of a mass grave -- I didn't make that part up.
From a history of the building:
In 1840, the first city cemetery was becoming too crowded. When the land was deeded in 1840, a 2nd public cemetery, called simply "City Cemetery", was designated. The cemetery was segregated, and some of the sections were designated for blacks, gunfighters/suicides/undesirables, Odd Fellows, Masons, and some lots for sale to the highest bidder. In 1867 Houston was hit by a plague of Yellow Fever, and many victims were buried in City Cemetery. The victims included Confederate soldiers, Union soldiers, and everyday people. In the late 1800s, the cemetery was so full that a third public cemetery was designated off of Allen Parkway. The third cemetery later ended up underneath Allen Parkway Village, a public housing project (I remember when that was re-discovered!). The City Cemetery received its last internment in 1904 and was de-certified soon afterward due to neglect. It is estimated that there are 5,000-6,000 people buried there, with 3,000 under the Elder St. location of Jefferson Davis Hospital.
Anyway, here's a Google map showing the building's location, for the curious. Google Maps
