Administration of the Property of the Holy See (Italian: Amministrazione dei Beni della Santa Sede, abbreviated ABSS) was a commission that, until 1967, administered the property of the Holy See other than the money in cash and Italian government bonds received when the Financial Convention attached to the Lateran Treaty of 1929 was implemented. On 15 August 1967, Pope Paul VI combined the Special Administration of the Holy See and the Administration of the Property of the Holy See into one office, the Administration of the Patrimony of the Apostolic See.
