Cisternerne Tickets

You go down through a glass pyramid in the grass of Sondermarken park, and the temperature drops with every step. Below the lawn lies a former drinking-water reservoir the size of a small cathedral, its brick vaults holding up a black lake, stalactites forming on the ceiling from the lime, water dripping somewhere in the dark. Cisternerne fills this strange space with a single large art installation each year, and there is nothing else quite like it in Copenhagen.

What is Cisternerne and what will you see?

Cisternerne is an underground exhibition space in a disused Victorian water reservoir beneath Sondermarken park in Frederiksberg. Built in the 1850s and used to supply Copenhagen's drinking water until 1933, it now hosts one large site-specific art installation a year. What you see is that single immersive work, staged among dripping brick columns, reflecting pools of water and near-total darkness.

The space itself is the star as much as any artwork. The vaults are damp and cold year-round, mineral stalactites hang from the ceiling where lime has leached through the brick, and thin sheets of water cover parts of the floor, so artists tend to work with reflection, sound and light rather than objects on plinths. Each commission is made for the reservoir and changes it completely, which is why regulars come back every year to see what the new installation does with the dark.

Because only one show runs at a time, it is worth knowing what is on before you go. Some years the work is walkable and dry underfoot, others it leans into the water and the gloom; the official site lists the current installation and its dates. Whatever the theme, the experience is slow, atmospheric and a little unsettling, closer to walking into a stage set than touring a gallery.

The yearly rhythm is central to how the place works. A new artist is commissioned to respond to the reservoir, the previous installation is stripped out, and for a season the whole underground is given over to one vision, which might be sound, sculpture, light, water or all four at once. That single-work focus is why two visits a year apart can feel like two completely different museums.

This is a place to feel rather than to read. There is little in the way of long explanatory panels, and that suits the setting: you move through the reservoir at your own pace, letting your eyes adjust, and the combination of cold air, echoing sound and low light does the work. Above ground, Sondermarken park and the neighbouring Frederiksberg Gardens make a green pairing once you climb back into daylight.

The history under your feet adds to the strange mood. When the reservoir was in use it held millions of litres of Copenhagen's drinking water behind these very columns, sealed and silent beneath the park, until the city moved to a cleaner supply and drained it in the 1930s. Left empty, the space slowly became what it is now, a cathedral of damp brick that artists have learned to treat almost as a living material rather than a neutral gallery.

How do tickets work and what does it cost?

Cisternerne is a ticketed museum run by the Frederiksberg Museums, and you buy admission at the entrance or on the official site. The exact adult price is not something we will quote here, because it varies with the current installation; check cisternerne.dk for the live figure. Anyone under 18 goes free. There is no rush to book a slot for most of the year, so it stays an easy, low-key visit.

This is an official museum listing, so there is no urgency and nothing to oversell. The single yearly installation means pricing and opening can shift between shows, and the honest advice is to look at the official page for the price and the current exhibition before you make the trip out to Frederiksberg. Under-18s enter free, which makes it a cheap family curiosity if the year's work suits children.

The table below shows the shape of a Cisternerne ticket rather than a fixed number, since the price moves with the programme. For the current adult price, the running installation and any timed entry during busy periods, the official site is the source. You can find it all on cisternerne.dk.

One honest planning note: the reservoir usually closes for a few weeks between installations while the next commission is built, so a visit in the changeover window can find it shut or half-dressed. The official calendar flags these gaps, another reason to check the current show before making the trip out to Frederiksberg rather than turning up on spec.

How long do you need, and what is a visit like?

A visit to Cisternerne usually takes 30 to 45 minutes. It is one large space with one installation, so you are not covering ground the way you would in a big museum; the time goes on standing still, letting your eyes adjust and taking in the atmosphere. Dress warmly, because the reservoir stays cold and damp whatever the weather is doing above.

Bring a layer even in summer. The vaults hold their chill and the air is heavy with moisture, so a sweater or jacket makes the difference between lingering and hurrying out. Footwear matters too: parts of the floor can be wet or uneven, and some installations route you along raised walkways over standing water, so sensible shoes beat sandals.

Give your eyes a minute at the bottom of the stairs. The reservoir is genuinely dark, by design, and the installation only reveals itself as you adjust. Once it does, the slow pace is the point. Many visitors do a loop, then stand a while in one spot to watch the light and reflections shift before heading back up into the park.

Comfort and access are worth a thought too. The reservoir is reached by stairs and the floor can be slick underfoot, so anyone unsteady should check the current access notes before the trip, and everyone does better taking the descent slowly while their eyes adjust to how little light there is. It is a place that rewards patience, so give it a few unhurried minutes rather than rushing the loop.

Know before you go: hours, closed days and getting there

Cisternerne lies under Sondermarken park in Frederiksberg, west of the city centre, with the nearest Metro at Frederiksberg station about ten minutes away on foot. It generally opens daily around 11:00, closing about 18:00, later on some evenings. In the low season of October and November it is closed on Mondays. Because hours change with the installation, confirm your date on the official site.

The trip out is short and pleasant. From Frederiksberg station on the Metro you walk into Frederiksberg Gardens and across into the adjoining Sondermarken, where the glass pyramids in the grass mark the way down. Several buses also stop near the park. The setting inside a green park is part of the appeal, since you can pair the underground cold with a walk among the trees before or after.

A couple of practical points. The reservoir is reached by stairs and is not fully step-free, so check access on the official site if that matters. It is cold and dark underground, as covered above, and there is no cloakroom to speak of, so travel light. Photography is usually allowed, though the low light tests most phone cameras, so do not expect crisp shots without a steady hand. Because the installation changes each year, a quick look at recent visitor photos of the current show is worth it before you decide, since some years lean bright and walkable while others are almost pitch dark by design. The at-a-glance table sums up the essentials.

What can you pair with Cisternerne nearby?

Cisternerne sits in Frederiksberg, a short way from the city-centre museums, so pairings split between its own leafy neighbourhood and a wider museum day in town. Right by the park is STORM, Denmark's museum of humour and satire, and the Frederiksberg Gardens and Copenhagen Zoo. For a fuller cultural day, the Glyptotek and the National Museum in the centre are a quick Metro ride away and are both on the Copenhagen Card.

Stay local first. A few minutes from Sondermarken, by the Frederiksberg Runddel, the small STORM (Storm P. Museum) makes a light, funny counterpoint to the cold reservoir, and the surrounding Frederiksberg Gardens are among the prettiest in the city. That combination, a dark underground installation and a bright park museum, fills an easy Frederiksberg afternoon.

If you want more heavyweight collections, ride into the centre for the Ny Carlsberg Glyptotek, with its ancient sculpture under a palm-filled winter garden, or the National Museum of Denmark for the country's full sweep of history. A Copenhagen Card covers both of those plus the Metro that gets you between them; you can check the inclusions on the Copenhagen Card site, and there is background on the reservoir on Wikipedia.
