Mimara Museum

The museum's own account puts its holdings at more than 3,500 objects; English Wikipedia, citing the museum's press material, gives a higher figure of over 3,750 across roughly 9,450 square metres, one of the largest exhibition areas of any art museum. The two figures are not reconciled in any source seen for this record. What is not in dispute is the breadth: archaeology from the Palaeolithic to the early Middle Ages, European sculpture from the 6th century onward, old-master painting from most of the major Western European schools, one of the largest glass collections in the region, and Chinese, Japanese and South and Southeast Asian art assembled at a scale unusual for a single private collector. The scholarly caveat that runs through every account of the museum, including this one, is that a meaningful share of the attributions announced at its 1987 opening have since been challenged or downgraded, and the museum itself does not discuss that history on its own site.

The Mimara Museum occupies the central block of what was built, from 1892 to 1895, as the Lower Town gymnasium complex on what is now Roosevelt Square, designed by the German architects Alfred Ludwig and Ljudevit Teodor Hulssner, specialists in school buildings for the Austro-Hungarian Empire. The Zagreb art historian and politician Izidor Krsnjavi had originally planned a much larger civic complex, a combined 'school forum' of teaching and museum institutions; money ran short, and only the simpler gymnasium block was built, opening to the public in 1895 on the occasion of a visit by Emperor Franz Joseph I. Until 1985 the building housed two working secondary schools, the First and Fourth Gymnasiums; the north and south wings of the wider complex still hold a school today. The building is listed as a protected cultural asset with Croatia's Ministry of Culture.

Between 1985 and 1987 the central block was adapted for museum use to house the art collection of Ante Topic Mimara, under a decision of the Croatian parliament and the Zagreb city assembly. The conversion kept the historicist facades and the atrium, built in the manner of an ancient Greek temple, that the school complex had given the square.

The museum's own account describes Ante Topic Mimara (1898-1987) as a collector, painter and restorer, born to a farming family in the Dalmatian hinterland, who spent most of his adult life outside Croatia, living in Rome, Paris, Amsterdam, Munich, Berlin, Tangier and finally a castle he bought near Salzburg. He began collecting art in the mid-1920s and, by his own account, built his holdings over five decades into more than 3,500 objects spanning classical archaeology, old-master painting, sculpture and decorative arts, Chinese art and oriental carpets. The museum's biography of its founder, published on its own site, presents the 1973 and 1986 donation agreements that created the museum as an act of patriotism by a lifelong emigre who never stopped thinking of himself as Croatian.

That account omits a great deal that outside researchers have since put on the record. Journalists and historians have identified at least two competing versions of Mimara's own early life, including a claim, reported by ARTnews, that he assumed the identity of a man named Ante Topic after that man's death in a Rome military hospital in 1918. His wife and collaborator, the German art historian Wiltrud Mersmann, worked at the US Central Collecting Point in Munich after the Second World War, the depot where looted and displaced European art was catalogued for return to its countries of origin.

A September 2001 ARTnews investigation by Konstantin Akinsha, drawing on US National Archives records, reported that Mimara appeared at the Munich Collecting Point in December 1948 claiming to represent the Yugoslav government's restitution mission, and by mid-1949 had obtained 166 objects, including 56 paintings, on the strength of claim lists that American investigators later concluded he and Mersmann had fabricated using information she had access to as a junior curator there. The Americans discovered the fraud only after the objects, and Mimara, had disappeared; fearing legal and political fallout, the US State Department chose not to notify the governments whose citizens, in some cases Holocaust victims, appear to have been the true owners. Decades later, ARTnews traced more than a dozen of those objects to museums in Zagreb and Belgrade, including paintings once in the collection of Baron Maurice de Rothschild and works assembled for the museum Hitler planned for Linz.

The same investigation reports that when the Mimara Museum opened in 1987, Yugoslav officials valued the 3,600-object collection at one billion US dollars and announced attributions to Michelangelo, Leonardo, Raphael, Botticelli and Velazquez; it also cites a 1987 ARTnews review by Andrew Decker in which art historians of the day dismissed most of the collection as fake or second-rate, with many attributions since downgraded. The museum's director at the time told ARTnews in 2001 that Mimara had never discussed the collection's origins with staff, and that he answered questions about provenance by saying that anyone who could prove ownership could take an object back. The museum has never addressed the Central Collecting Point allegations on its own site.

Independent of the dispute over individual attributions, the range of material is not contested: more than 3,500 objects, on the museum's own count, spanning the prehistoric period to the 20th century across roughly 9,450 square metres. The lower floors hold archaeology, from a Palaeolithic bone figurine through Mesopotamian, Egyptian, Greek, Etruscan, Roman and early Christian material, and European sculpture from the 6th century onward. The upper floor holds old-master painting organised by national school; Italian, Flemish, Dutch, German, Spanish, English and French painters are all represented, alongside a large glass collection spanning four millennia and one of the largest holdings of Chinese and other Asian art in Southeastern Europe. A drawings collection and further galleries of ivory, ceramics, porcelain, furniture, textiles and carpets fill out the museum's own account of its holdings.

The museum shut its doors to visitors on 17 March 2020 because of the Covid-19 pandemic; the notice the museum posted that day, still live on its own site, told visitors it hoped to reopen as soon as it safely could. Five days later, on 22 March 2020, a magnitude-5.5 earthquake struck Zagreb, and the museum's own historicist building, part of the same complex that had stood since 1895, was among the cultural properties seriously damaged: the roof and the second-floor grand hall, where many of the old-master paintings hang, took the worst of it, and some works on display were themselves damaged. What had been announced as a temporary pandemic closure became a six-year structural one.

The Croatian Ministry of Culture and Media has treated the Mimara Museum's repair as part of a much larger post-earthquake programme; at a closing conference held at the museum on 22 July 2026, the ministry said the wider Zagreb and central Croatia effort had by then rebuilt, or was still rebuilding, more than 50 museums, archives and libraries and more than 500 individually protected buildings and monuments. At that same conference the museum's director, Tajana Plese, and the project's lead architect and conservator presented the completed structural strengthening, energy retrofit, and conservation and restoration work on the building's historic fabric, along with a new permanent-display concept organised around three themes: nature, society and belief. A time capsule containing coins, a newspaper, a shop receipt and a charter signed by the Croatian prime minister, two government ministers and the museum's director was sealed into a display case as the collection's newest object, recording the building's repair.

The museum's own announcement of that conference states that, with construction finished, preparations are now in their final phase ahead of a reopening planned for October 2026. The museum's site describes this only as a plan, not a fixed date, and gives no fallback if the target slips; as of this record's most recent check, the museum's own homepage still displayed a standing notice that it remains closed to visitors.

The practical detail on this page describes the museum as it operated before the March 2020 closure, because no post-reopening visitor information has yet been published. Admission was inexpensive by regional standards, with free entry for ICOM and Croatian Museum Association members and on set free days each year; the museum sat on the same tram stop, Rooseveltov trg, as several other Zagreb institutions, with city parking in the surrounding streets rather than at the museum itself. Photography without flash was allowed throughout, and a cafe and museum shop operated in the building alongside the galleries. None of this can be booked or relied on until the museum itself publishes updated information; a reader planning a visit around the announced October 2026 date should check the museum's own site again closer to the time.

Visitor accounts from before the 2020 closure describe an unusually large, wide-ranging private collection, shown across three uncrowded floors of a grand 19th-century building, at a low admission price with helpful staff. Set against that runs a controversy as old as the museum itself: since its 1987 opening, historians and journalists have repeatedly challenged the authenticity of a large share of the paintings and the honesty of the founder's own account of how he acquired them.
