Most cemeteries have graves which are dug out of the ground. However, a few cemeteries have tombs that are all above ground. Is there a single word that describes these types of cemeteries?
Mausoleum is not the answer I'm looking for, because a mausoleum is a single building that holds one or more tombs. I'm looking for the word for the land that would hold many mausolea, for example.Edit
For example, all the cemeteries in New Orleans are above ground because New Orleans is built below sea level in a flood plain. The tombs are all called vaults. All the references I can find refer to the land incorporating the vaults are above-ground cemeteries. But I thought one time I heard a single-word term for the same. Here is an example.
