Always question why there’s an old stone wall along a major roadway in St. Louis! I was doing some research on a gentleman whose death was recorded in the “Deaths Outside of St. Louis,” but yet he was buried in Bellefontaine Cemetery the next day. He clearly did not die very far away from the city, and closer inspection revealed he died of phthisis–tuberculosis–at the Mount Rose Sanitorium at 9101 South Broadway, which is now the small school district of Hancock Place’s elementary school.
It looks like your average medical institution of the time, constructed in 1902 and administered by the Sisters of St. Mary; compare with the form of the original St. Anthony’s.
There is a new building constructed on the site of the original hospital, which prided itself in the continuous wiping down of surfaces. There was tile on all the walls and floors, and no carpet or tapestries to absorb infectious liquids. It was surprisingly advanced for the time and for its understanding of germ theory.
The architect seems to have harkened back to the original design of the sanitarium with the concrete, Brutalist tower. I think some of the pavilions out front were constructed when the hospital was still active.
Nearby are simple houses that I suspect were occupied by employees, as this was a fair distance outside of the urban core, even with a streetcar connection.
