National Museum of Decorative Arts

European decorative art of the sixteenth to twentieth centuries is the core of the museum's roughly 6,000-object collection, assembled first by Matias Errazuriz Ortuzar and Josefina de Alvear during a decade living in Europe before 1916 and expanded since the museum's 1937 opening through gift and bequest. Its particular strengths are period furniture and decorative objects shown in the rooms bought to hold them rather than in cases, French eighteenth-century decorative arts (porcelain, bronze, tapestry), and a collection of European portrait miniatures that independent reference sources describe as the most important of its kind in the Americas. Painting and sculpture are present but secondary to the decorative arts and to the house itself, which the museum and its visitors alike treat as the primary exhibit.

The house the museum now occupies was built for a single household. Matias Errazuriz Ortuzar, the son of a prominent Chilean family, married Josefina de Alvear, granddaughter of the independence leader Carlos Maria de Alvear, in Buenos Aires in 1897. The couple then spent roughly a decade living in Europe, where they assembled a substantial collection of European and Asian art and decorative objects - the core of what the museum shows today. On their return to Buenos Aires they commissioned the French architect Rene Sergent, who had built town houses for European aristocracy but never previously worked in Argentina, to design a residence that could hold what they had bought and match the life they had lived abroad.

Sergent's design, built between 1911 and 1917 with construction delayed by the First World War, is an eclectic French neoclassical composition drawing on eighteenth-century French models associated with the architect Jacques-Gabriel. Giant Corinthian columns run across the two principal levels of the four-storey facade: a ground floor with arched openings onto the garden and terrace, used for entertaining, and a first floor of family apartments above it. Sergent fitted the house with technology unusual for Buenos Aires at the time - two lifts, central heating and a centralised vacuum system - built into a house designed above all for comfort and display.

The Errazuriz Alvear family lived in the house for eighteen years, using its principal rooms for the recitals, receptions and charity balls typical of Buenos Aires high society in the 1920s. Josefina de Alvear died in 1935; her widower Matias Errazuriz Ortuzar then sold the house and part of its collection to the Argentine state in 1936. The National Museum of Decorative Arts opened to the public on 18 December 1937, established by national law (Law 12351), with the residence itself becoming the museum's principal exhibit alongside the objects inside it.

The museum operates today as a national institution under the Secretaria de Cultura de la Nacion, the same federal body that runs the Museo Nacional de Bellas Artes and the Museo Historico Nacional; its current director is Hugo Pontoriero, previously the museum's general curator. This national status is worth stating plainly because at least one widely read reference source describes the museum incorrectly as a municipal institution of the City of Buenos Aires - the museum's own domain, its email addresses (ending mnad.gob.ar for its director's office) and the Spanish-language reference literature all place it under the national Ministry of Culture, not the city government.

The visiting route runs through the rooms much as the family used them. The Great Hall, a double-height space with a coffered wooden ceiling and a first-floor gallery running around it, held the household's largest gatherings and still carries sixteenth-century tapestries on its end wall beneath wrought-iron candelabra. The dining room, finished in Italian and French marble and modelled on the state rooms at Versailles, and a ballroom in a Regency-to-Rococo transitional style complete the ground-floor sequence used for entertaining.

Upstairs, the family's private apartments include one of the house's most unusual rooms: a small Art Deco boudoir commissioned around 1916 from the Catalan painter Josep Maria Sert for the Errazuriz Alvear's teenage son, Matias Errazuriz Alvear, who had met Sert through his mother's circle in Paris and asked his parents to let Sert decorate the room in full. Sert gave it a deep opaque blue ceiling with a crackled gilt finish, carried on two gilt beams, walls stuccoed to imitate the dark porphyry the Romans used, a mirrored fireplace surround, and four painted panels on the theme of La Comedia Humana. The room survives essentially as Sert left it and is among the more complete examples of his decorative work open to the public anywhere.

A room the museum calls the Salon de Familia houses its collection of European portrait miniatures, worked in watercolour and gouache on ivory and vellum across four centuries; independent reference sources describe it as the most important collection of its kind in the Americas. Outside, a formal French garden laid out by the landscape designer Achille Duchene extends the ground-floor reception rooms into the grounds, and the museum's cafe opens onto it. The house's former service floor, in the sub-basement, is now used for rotating temporary exhibitions - most recently a 2025 show on Italian tourist-poster art of 1920 to 1950 and a 2025 retrospective of the Argentine designer Alberto Churba.

The roughly 6,000 objects the museum now holds began with what Matias Errazuriz Ortuzar and Josefina de Alvear bought during their years in Europe and sold to the state along with the house in 1936; the collection has grown since 1937 through gifts and bequests from other collectors. Its declared strength is European and Asian decorative art of the sixteenth to twentieth centuries - sculpture, painting, tapestry, arms, books, ceramics, furniture and miniatures - shown for the most part in the rooms it was originally bought to furnish rather than in glass cases.

The paintings include El Greco's Jesus Bearing the Cross and a portrait by Edouard Manet of Abbe Hurel. The sculpture collection pairs a bronze by Auguste Rodin, The Eternal Spring, with an ancient Roman Minerva, an unusual juxtaposition of antiquity and Belle Epoque taste kept in the same rooms. Decorative highlights cited across the sources for this page include a bronze mantel clock given as a wedding gift to Louis XVI and Marie Antoinette, Sevres and other French porcelain, and Gobelins and Beauvais tapestries alongside the sixteenth-century pieces in the Great Hall. Much of the collection is kept in storage rather than on permanent view, and the museum rotates what is shown to manage light exposure on the older textiles and works on paper.

On 1 March 2022 the museum's then director, Martin Marcos, reported that a group of objects had gone missing: three nineteenth-century Austrian porcelain vases from the Empire anteroom, six pieces of twentieth-century Swedish glass and crystal from a sub-basement storage area that had no security camera coverage at the time, and two seventeenth-century Spanish Old Master paintings, San Jose con el Nino from the school of Murillo and an anonymous Retrato de Infanta. The case was opened as file 462/22 in the federal criminal courts under prosecutor Gerardo Pollicita, and Argentine press covering it at the time called it a robo hormiga - an ant theft, meaning a slow accumulation of small losses rather than a single break-in.

The Ministry of Culture responded by placing the museum under a thirty-day intervention, replacing Marcos with Maria Isabel Baldasarre, the national director of museums, who ran a full inventory and had closed-circuit cameras installed. Marcos disputed his removal in court, seeking reinstatement. By the two-year mark, in February 2024, La Nacion reported that none of the roughly twenty missing pieces had been recovered, that Interpol's search remained open, and that the museum had gone through four directors since the theft, with Hugo Pontoriero, the former general curator, then newly appointed. The national heritage director Liliana Barela was quoted at the time attributing this kind of loss to people with inside knowledge of a collection's contents, and argued that inventory discipline mattered more than security hardware alone. No reporting found for this page updates the case beyond that February 2024 account, so the current whereabouts of the missing pieces and the present state of the prosecution are not established here.

The museum functions as a working national institution rather than a fixed period display: its own news page lists a continuous run of temporary exhibitions and public programming through 2024 and 2025, including an annual yearbook of the year's activity in the Palacio Errazuriz Alvear, participation in the citywide Noche de los Museos, and workshops for children and school groups run through a dedicated education department. Admission remains free for all visitors with no advance booking, a point every visitor source consulted for this page treats as central to how the museum is experienced - reviewers across 2025 and 2026 repeatedly describe it as a highlight found by accident precisely because it does not carry the profile, or the entry queue, of the larger museums nearby in Recoleta. The building's condition and the completeness of its rooms are the most consistent draw; the collection inside them draws steadier, more measured praise, and the unresolved 2022 theft remains the clearest unanswered question hanging over an otherwise well-run house museum.

Visitors are consistently more enthusiastic about the house than about any single object in it: TripAdvisor reviews from across 2025 and 2026 describe the Palacio Errazuriz Alvear as one of the best-preserved Belle Epoque interiors open to the public in Buenos Aires, and repeatedly flag free admission as a reason it over-delivers against expectations set by its low profile on standard tourist itineraries. A minority of reviewers, while still positive about the building, say the collection itself does not match the setting. Separately from visitor sentiment, the museum carries a real institutional blemish: a 2022 theft of at least twenty pieces that remained unrecovered and under federal investigation as of the last reporting found for this page, and four changes of director in the two years that followed.
