In "The Cask of Amontillado" where does Montresor take Fortunato to get revenge?

Montresor has a
long-standing problem with Fortunato.  We do not know what it is, because we are never told. 
Montresor knows that Fortunato is a wine connoisseur, and tempts him with an Amontillado - a
type of sherry wine.  Montresor wants Fortunato to taste the wine to see if it's the real
thing.  Montresor lures Fortunato into Montresor's family's catacombs in search of the wine. 
The catacombs are deep underground.  Once there, Montresor shackles Fortunato to the wall and
proceeds to brick Fortunato into that recessed area.
