Oops. Forgot to mention, the coffin goes first to the Sistine Chapel for a metaphoric recognition of the passing of the torch, before it goes to the Basilica. The Sistine Chapel is where the conclave will be held after the funerals.

I know it is being reported that the silver hammer ritual was discontinued by John XXIII, and that it is not included in JP's Universi Dominci Gregis. However, rumor in certain Catholic circles has it, that it would be done.
