Update: I went back and revisited the cemetery and mausoleum in July of 2020.
The oft-vandalized Miles Mausoleum, southwest of Columbia, Illinois, has recently been cleaned, and security cameras have been installed to ward off future desecration of the tomb. Sadly, all of the remains have been removed, as it was no longer safe to inter them there.
The mausoleum is built into the side of the hill, high above the river bottoms of the Mississippi. I find the Ionic capitals interesting; they are corner versions of the ancient Greek order, despite being on the side of the facade. Only one is still fully intact.
The non-profit who maintains the cemetery is working to fix the erosion and deterioration of the cemetery.
The first burial was in 1806, and the last one in 1978; the mausoleum was built in 1858.
The broken column, visible in front of the mourning woman below, can in relief sculpture and in actual monuments represent a life cut short in its prime.
