Wow, I just discovered one of the most beautiful cemeteries in the St. Louis area, and also one of the oldest: New Mount Sinai Cemetery, located just beyond the city limits out Gravois, where there are of course many other burial grounds.
And then, in what is probably a first in St. Louis, there is a double mausoleum, with two families joined together in eternity with two front doors…
…while around back there are two circular/square windows lighting the interior.
In the center of the cemetery is this stout and well-maintained house or office with an impressive turret and glazed tile roof.
I suspect this building might have held coffins in the winter before burial, as was common before mechanical earth movers (yes, I’m aware that some people built fires over graves to thaw the earth), but I have firsthand reports from cemetery staff in St. Louis that you would wait until the spring.
The gates are probably much later from the early Twentieth Century, but fit in well with the earlier architecture.
