The Treasure Museum of the Basilica of San Francesco in Assisi is located in the historic church of the city center. The collection is called "Treasure" because it includes paintings, textile artifacts and goldsmiths of great value and linked to the history of the Basilica. Today the collection is kept in the Gothic hall of the Sacro Convento and is mostly composed of European and Eastern sacred goldsmiths. The heritage is rich in reliquaries, crosses, two Arab dossals in red and yellow silk, the frontal of Sixtus IV, eight Flemish tapestries, medieval glazed majolica, historiated tables and four synopies by Roman and Sienese masters. The Museum was enriched in 1986 with 57 tables and a marble bas-relief. Important is the donation of Frederick Mason Perkins, art historian, who during his life collected paintings of the Venetian and Tuscan school of the fourteenth and fifteenth centuries. Of great interest is the illuminated Parisian missal with the evangelary and the letters of St. Louis IX.
