The glass collection of the Ajuda National Palace comprises about 12.500 pieces from the former Royal House assets. It includes utility and decorative glass, light fixtures and glass panes. Holdings date mainly from the second half of the 19th and the early 20th century, corresponding to the period when the Ajuda Palace was inhabited by Queen Maria Pia - namely between 1862 and 1910. Her judicious orders and her particular taste for glass are reflected in the large tableware sets, which have a prominent role in this collection. They include examples originating from the major European glass trading and manufacturing centers of that time, among which: Bohemia (Moser), Italy (Venice Company / Murano, Salviati, Fratelli Toso and MQ Testolini), France (Baccarat, Daum, Gallé, Nancy School), Spain (La Granja and the region of Catalonia), Austria (J & L Lobmeyr), England (Thomas Webb & Sons), Germany and Portugal. Consisting mainly of pieces produced from the glass blowing technique, they illustrate the main trends of the time, such as the Germanic, the “Islamist", the "façon Venise", the "façon d 'Angleterre" styles, among others. The glass collection is further enriched with heraldic decorative elements, individual or joint monograms belonging to King Luís and Queen Maria Pia, which confer it a particular and unique character.
