The Museum Building

Upon arrival, the museum stands out due to its location. The CosmoCaixa museum is housed in an old building from 1909. It was designed by architect Josep Domènech i Estapà in Modernista style as an asylum for the blind.

Inside is a modern museum with no less than 5 different floors that go deep and a huge courtyard called Plaça de la Ciència.

What certainly stands out at the entrance is the enormous staircase that goes down and where a huge tree from the Amazon hangs.

The Permanent Collection

The CosmoCaixa museum has a permanent collection on the lower floor where visitors can endlessly experiment and discover new things about science and physics.

In the Sala Univers, visitors take a journey through the history of matter, from the Big Bang to the present. The permanent exhibition is divided into four areas: inert matter, living matter, intelligent matter, and civilized matter.

Here, visitors can experiment to their heart’s content to better understand the laws of physics and the phenomena of daily life: from light, sound, weight, and speed to gravity, microorganisms, and ecosystems.

At the geological wall (the Mur Geològic), it is also possible to see different pieces of rocks from all over the world, while at the Antarctic base (the Base Antàrtica), a photo exhibition can be found about the exploration trips to the South Pole.

But the most fun is undoubtedly the flooded jungle, the Bosc Inundat, which simulates the ecosystem of the Amazon and where you can walk through and spot all kinds of fish, animals, and plants. But watch out, because occasionally there is a heavy downpour!

Events at CosmoCaixa

Regularly new temporary exhibitions are held at the CosmoCaixa museum on numerous relevant topics. These can be visited with your general admission ticket.

At the CosmoCaixa museum, daily lectures, films, theater performances, and workshops are given on a wide variety of topics. From the universe to the earth, humans, or nature. These activities, however, are only offered at certain times and separate tickets must be purchased for them.

It is therefore advisable to take a look at the museum’s agenda before visiting it. This way, you know what is planned for that day and you can reserve tickets in advance. Most activities also include an age indication and the language, but be aware, as most of these activities are offered in Spanish or Catalan.

Children’s Activities at CosmoCaixa

In addition to the interesting permanent collection, the CosmoCaixa museum offers all kinds of workshops and theater performances for children from 3 years old.

The museum also offers space for children to investigate and learn new things, for example in the Planetarium, where they can take a journey through the universe, the Sala Materia, where they can turn into real scientists, the Creactivity, where they can design things themselves, or the Toca Toca, where they can do all sorts of sensory activities.

For all these activities, a separate ticket applies. Check the agenda for availability and corresponding age.

History of CosmoCaixa Museum

The CosmoCaixa Museum was opened in 1981 as the Museu de la Ciència de Barcelona on the site of the former asylum for the blind (L’Empar de Santa Llúcia). The institution had existed for 75 years in a beautiful building designed by modernist architect Josep Domènech i Estapà.

The museum belonged to the Fundació La Caixa (a charitable organization of the Catalan bank La Caixa) and was the first interactive science museum in all of Spain.

After a thorough renovation and expansion of the museum in 2004, it changed its name to CosmoCaixa and became one of the most prominent science museums in all of Europe.

In 2006, the CosmoCaixa museum won the award for the best museum in Europe and has since been an example of modernity and sustainability.

Today, the CosmoCaixa museum is one of the coolest science museums in Spain and a must-see if you’re traveling with children.
