context_page_description: The Redoubt of Mount Cintra, commonly known as the Fort of Sacavém, is located in the town of Sacavém in the municipality of Loures in the Lisbon District of Portugal. It is situated immediately to the north of Lisbon. The fort’s construction began in 1875 and was completed in 1892. Since 2015 it has served as the National Archive for Portugal’s Directorate General of Cultural Heritage.
context_section_description: Adaptation to its new function lasted until 2007. Following the system used by Library and Archives Canada, the fort now holds two of the country's largest archives of cultural heritage and architecture: the Information System for Architectural Heritage, with a documentary collection composed of more than 7 kilometres of shelves, 500,000 documents and 300,000 photographs of national buildings and monuments; and the Photographic Documentation Archive (ADF), which includes a total of one million images of various items held in national museums and palaces. The library is unique in the country, and is devoted to the dissemination of information on built heritage, especially in the areas of conservation, restoration and urban rehabilitation.
  Documents are first held for 21 days in a closed chamber to ensure they are free of any type of infestation and then transferred to another chamber where they are further quarantined for 40 days. Each document is then subjected to a process of hygiene where conservationists clean them. Once certified free of disease they are ready to be archived and inventoried and then stored in one of five different environments with different levels of humidity, air temperature and oxygen, according to the requirements of the individual documents. 
  The Sacavém fort has attracted a wide variety of birds, some of which nest there. Visits to the fort are not permitted unless for purposes of using the archives.
