Closed Temporarily Is Not a Date

A closed museum is still the answer to the question of where an object is

Every record in this archive ends with a line saying where the object is now, and for 254 of the 285 published records that line names an institution. The line stays true when the institution shuts its doors. It simply stops being useful, because what a location line is really for is telling a reader how to go and stand in front of the thing.

We started recording an open or closed state on every venue because of that gap. The archive now holds 271 museums, palaces and libraries with their addresses, opening hours, admission tiers and current status, each confirmed against the institution's own page or its own public statements. Twenty-two of them are closed.

What we did not expect was how rarely a closure comes with an end. The phrase these institutions use, almost without variation, is closed temporarily. It is a claim about the eventual outcome and it says nothing whatever about when.

Twenty-two museums here are shut, and one has a firm date

Of the 22 closed venues in this archive, one carries a reopening date we grade as firm, three carry a date that is published but soft, and eighteen carry no date at all. The firm one is the shortest closure on the list by a wide margin.

The Mauritshuis in The Hague is closed from Monday 24 August through Sunday 20 September 2026 for maintenance work, which its visit page states in exactly those terms. Four weeks, both ends given, and a museum that will be open again before the end of this month. It is the only closure here precise enough to plan a trip around, and it is precise because it is small.

Read down that table and the relationship is the wrong way round from what a visitor would assume. Precision falls as the stakes rise. The four-week maintenance shutdown publishes a day. The decade-long structural rebuild publishes a mood.

The longest closures are the ones with no date

Museum Boijmans Van Beuningen in Rotterdam has been closed since 2019, and its own renovation page says the work will take no fewer than ten years to complete. It does not name a reopening year. We checked the page on 6 September 2026 and that is still the position: asbestos removal and design work by Mecanoo, phases described, no date offered.

The Neue Pinakothek in Munich closed the same year. Its own page says the museum is undergoing major renovation and is therefore currently closed, and points visitors to the state building authority for updates. It gives no reopening date either. Our own note from an earlier pass recorded a planned 2029 taken from the visit page, and that year is no longer stated there, which is a fair illustration of how quickly this kind of information decays.

The National Art Gallery of Albania is the clearest case on the list. The Ministry of Culture announced the closure on 18 October 2021 and put the works at two years, which meant the end of 2023. Nothing has revised that publicly since. The gallery holds the deepest collection of Albanian Socialist Realist painting and sculpture anywhere, more than fifty artists documented on a single pre-closure visit, and it has now been shut for longer than the closure was ever meant to last.

Berlin published a date, and then published a second one thirteen years later

The Pergamonmuseum is the exception that shows why the rest stay silent. The Staatliche Museen zu Berlin have published a specific reopening, 4 June 2027, and they have published what it does and does not cover.

It covers the north wing and the central building: the Pergamon Altar and the Hellenistic hall of the Antikensammlung, and the complete presentation of the Museum fuer Islamische Kunst, including the Aleppo Room, the Mschatta facade and the Alhambra Dome. It does not cover the south wing, where the main holdings of the Vorderasiatisches Museum remain. Those get an interim showcase in the Schlueterssal, previewing a display the museum says will arrive in the south wing from 2037.

The refurbishment began in 2013 and is the building's first comprehensive one in more than ninety years. Counted from that start, the north wing returns after fourteen years and the south wing after twenty-four. Berlin has been more honest than almost anyone else on this list, and the honest answer is a quarter of a century.

A target that has passed is worse than no target

The National Museum of Iraq in Baghdad shows the failure mode that a published date creates. In December 2025 the State Board of Antiquities and Heritage gave a target of early 2026, with renovation reported at 90 per cent complete. On 9 February 2026 the Ministry of Culture's own Tourism Authority, speaking on the record to Iraq's state news agency, described the museum as still closed.

A reader who found the December statement and stopped there would now hold a confident, specific and wrong belief about a museum holding some of the most important objects to survive the looting of 2003. Silence would have left them uncertain, which is the correct state. This is why we grade a reopening as firm or not firm rather than simply recording the date, and why the Mauritshuis is the only entry on this list to earn the first grade.

What a closure does to the objects inside it

Four published records in this archive currently sit inside closed museums, and each is affected differently. The Weary Herakles is at the Antalya Museum, whose 1972 building was demolished in September 2025 for a rebuild on the same site, and whose holdings have been moved to temporary on-site storage. A volume of the Yongle Dadian is at the Chester Beatty Library in Dublin. The Cheapside Hoard belongs to an institution that closed its London Wall building on 4 December 2022 and has not yet opened at Smithfield.

Girl with a Pearl Earring is the instructive one, because the painting and the building are not shut for the same period or for the same reason. The Mauritshuis is closed for four weeks. The Vermeer is off display from 15 August to 4 October 2026, a fortnight either side of the building's closure, because it is travelling to Japan while the museum is shut. The object's location line and the building's opening hours are two separate facts and neither one answers for the other.

That is the practical lesson for anyone using a location line as a plan. A record can tell you truthfully that an object is in a named museum in a named city while the museum is shut, the object is on another continent, or both.

How to read a closure line

Treat closed temporarily as a statement of intent with no duration attached, because that is all it is. On this evidence the phrase covers a four-week maintenance shutdown and an eleven-year structural rebuild with equal comfort, and the institutions using it are not distinguishing between them.

Look for a date, and then ask what the date is attached to. A firm date names both ends and comes from the institution's own visit page. A soft date names a year, a season or a wing, and is frequently a construction milestone rather than a promise to the public. Berlin's 4 June 2027 is real and covers half the building.

Check when the statement was made, and check it again. Two of the closures here have already outrun their own announced schedules, one silently and one on the record. Before travelling for a single object, confirm on the museum's own page in the week you plan to go, and confirm that the object itself has not been lent somewhere else while the doors were shut.

Why this archive is free to read

We do this for everyone who loves art. The people who have studied it for years, and the people who just stopped to look. Iconotheca exists so that what we learn belongs to all of them.

Nobody pays us for this. No ads, no sponsors, no commercial interest. These works belong to all of us, and we would rather share them with as many people as we can than keep them to ourselves.

If it gave you something today, tell us to keep going. Follow us, leave a like, or write a positive comment. We read every one, and they are what keeps us going.
