St. Patrick Cemetery No. 2

Not quite sure how to rate a cemetary. I think they’re interesting for various reasons, and in New Orleans particularly because the plots are all above ground and have so much character. I’m intrigued by the ornate designs of some of the headstones and the grand stature of the mausoleums.
I wonder what it all means; why a family chooses something very simple and another chooses something so grand. Is it to flaunt wealth and status even after death? Do people just buy what they can afford? Why are there fences/​chains around some and not others? Do people get buried with their parents and siblings anymore, leaving their spouses and children to be buried elsewhere? And for those who have been deceased since or before the early 1900s… do they still get visitors?
In New Orleans there are cemeteries all around so finding one to visit should be easy, but check the internet because some have restricted hours and charge a fee.
