You may have heard about the tomb they unearthed in Greece recently. Its very large and in fairly good condition considering 2000 odd years have passed since it was built. Livescience has a very good pictorial spread of the tomb over on their site. Enjoy it here.
It will give you a little taste of what these areas are, or were, like when you next start mapping out your dungeon. Perhaps less rooms devoted to the wizard's chambers, and more to burying the dead.
This is a closer runner up to the Viking Longship I'm wanting everyone to burn me when I pass, if not that, then perhaps a tomb like this.
