The Ajuda National Palace, a neoclassical building from the first half of the 19th century, was inhabited by the Portuguese Royal Family until it was closed in 1910, due to the fall of monarchy. Open as a museum since 1968, it is representative of a royal household of that time, showing a significant collection of decorative arts, especially from the 17th to 19th centuries: jewelry, textiles, furnishing, ceramics, glass, as well as painting, sculpture and photography. The National Palace of Ajuda has two functions: one being that of a museum, through which its history and collections are available to the public; and the other being to show visitors the royal residence as it was until 1910.
