Recently I attended a funeral at St. Louis Cemetery No. 3 in New Orleans. Because the city is below sea level, burials are often in tombs like the one below or mausoleums. In this photo the tomb is open. A metal casket is visible. No ghosts were captured in this shot.

By the way there are so many already buried in this one tomb, there's a process to request burial in it. That includes proving lineage to the family.
