The National Inventory of the Cultural Property of the Maltese Islands (NICPMI) is a heritage register listing the cultural property of Malta. The inventory includes properties such as archaeological sites, fortifications, religious buildings, monuments, scheduled property and other historical buildings. The offices of the Superintendence were located at 138, Melita Street, Valletta until 2008, and are now found at 173, St. Christopher's Street, Valletta.
The inventory was established on 16 December 2011, according to article 7(5)(a) of the Cultural Heritage Act, 2002:
(5) It shall be the function of the Superintendence:
In the book Il-Mit Pawlin u l-Abbuż tal-Istorja Maltija (The Pauline Mythology and the Abuse of Maltese History), Author Mark Camilleri criticizes the Superintendence for supporting Pauline mythology by presenting the 12th-17th centuries tales purported by Giovanni Francesco Abela as fact, and for supporting the idea that Christianity in Malta has been continuous since the supposed shipwreck in Malta which contemporary historians such as history Professor Godfrey Wettinger discredit as pseudo-history. Camilleri wrote that the Superintendent, and those resposable for the NICPMI, set aside archeological research related to the Arab period in Malta (870-1091). When requesting information of the Arab period remains in Malta, under the access to information act (based on the Aarhus Convention), the Superintendence refused to cooperate.
