The private residence of the Pope in the Vatican City, that is his apartment in the Apostolic Palace beside the Basilica of St. Peter is left vacant upon the death of the Pope, or in this case, the retirement of the reigning Pope, which began the sede vacante, during which no Pope is present.

Therefore, in order to avoid fraud and manipulation of papal documents of the previous Pope, and to prevent release of items that can only be done by the new Pope, the Pope’s Apartment is sealed, by a special officer of the Roman Curia, that is the Camerlengo (Chamberlain) of the Holy Roman Church, who is now Cardinal Tarcisio Bertone, who is also the Secretary of State of the Holy See.

The Camerlengo is the leader of the sede vacante transition period, and working in conjunction with the Dean of the College of Cardinals. His duties include sealing the Pope’s apartment and the destruction of the Pope’s Ring of the Fisherman, both of which meant to ensure no fraud documents can be released in absence of the Pope.

The sealing is done as soon as the Pope passed away or stepped down, and done in the presence of the Vice-Camerlengo, who is now Archbishop Pier Luigi Celata, and sealed with a silk string tied and sealed with a wax seal to ensure no one can enter the room, with the unbroken wax seal as evidence.

The room will only be opened again and the seal broken after the conclave is completed and a new Pope is elected.
