Catacomb
Crypt.
In the past, people called that area a graveyard. Today, it is more common to call the burial area a cemetery. One piece of a cemetery is a grave or a grave plot, meaning a plot of ground with a set size that is sold as a plot for burial purposes. A person or family can buy one or more plots in a cemetery. Most people who buy 2 or more plots buy them side by side as a family plot.
The word that will correctly complete the analogy is "cemetery." Just as a mausoleum is a type of tomb, a maverick is often associated with nonconformity or independent thinking in a cemetery.
Another word for artifact is relic or antiquity.
Another word for an Egyptian tomb is "pyramid."
The correct spelling is "buried," and it is the past tense of the verb "bury," which means to inter a dead body or place something underground.
It is a Catacomb.
