a burial place

a hidden grotto

a ghostly hideout

The denotative meaning of the word "catacomb" in the story is "a burial place." This is evident in the story as the catacomb is described as a maze of tunnels and chambers where the Montresor family's ancestors are buried.

Yes, I am very sure that the denotative meaning of the word "catacomb" in the story is "a burial place." It refers to an underground cemetery or burial place, which is consistent with how the catacomb is described in "The Cask of Amontillado."
