The Tapestry and Textiles Restoration Laboratory is a modern infrastructure of lay people and three nuns. They are all highly-specialized in the restoration of textile products.

Pope Pius IX founded the restoration laboratory in 1926. At the behest of Pope Benedict XV, he entrusted the laboratory and the task of conserving the important pontifical collection to the care of the Franciscan Missionary Sisters of Mary. At the time, the above “collection” consisted mainly of tapestries. Over time, the collections included additions of many textile artefacts, embroideries, fabrics, sacred wallpapers, and furnishings. This endeavor expanded the specifications of the laboratory.
Performed restoration operations are divided into different stages. It starts with an accurate graphic and photographic documentation, followed by the chemical-physical investigations carried out in collaboration with the Scientific Research Cabinet. 

These investigations aim to identify the nature of the fibers, define their state of conservation, and recognize the original dyes. These are all necessary actions before proceeding with the next stages of the restoration.

At the end of this study phase, we continue with the restoration work. We then carry-out a mechanical cleaning (suction), and remove old restoration interventions. After, we proceed with chemical cleaning by washing in water and detergent solution. After dyeing yarns and supports, we consolidate damaged areas. The restorations ends with the lining and creation of the display system. The phases described above change according to the peculiar characteristics of each work that undergoes restoration. The laboratory staff also takes care of ordinary maintenance of the prompt intervention and the temporary organization of exhibitions of textile works that belong to the Holy See.
