What is CosmoCaixa?
CosmoCaixa is Barcelona’s great science museum: a space dedicated to bringing science closer to everyone in an interactive, fun way for all ages. Run by the “la Caixa” Foundation, it’s one of the most important science museums in Europe and, without doubt, one of families’ favourite plans in the city. Here you don’t just look at science: you touch it, experiment with it and play with it. From the cosmos to the Amazon rainforest, from the planet’s geology to Antarctica, the museum offers a fascinating journey through knowledge in a building as beautiful as its content.
The building: from Modernism to a science museum
CosmoCaixa’s home is one of its attractions. The original building, by architect Josep Domènech i Estapà, was built between 1904 and 1909 as an asylum and is a notable example of Modernista architecture. After operating as the Science Museum from 1981, a major expansion in 2004 preserved the historic Modernista hall and added new underground spaces, turning it into today’s museum, spread over several floors with an outdoor courtyard overlooking the city. The result is a dialogue between the century-old building and contemporary architecture in the service of science communication.
What to see at CosmoCaixa?
The Flooded Forest
It’s the museum’s icon: a faithful recreation of over 1,000 m² of Amazon rainforest inside a greenhouse, with more than 80 plant species and dozens of animal species native to Brazil (piranhas, crocodiles, amphibians, tropical birds, insects…). You walk through it, even below the water level, with its humid climate, its rainfall and its real vegetation. A unique immersive experience.
The Universe Room and the Matter Room
A journey through the great story of science: from the Big Bang and the evolution of the cosmos to the appearance of life, the first neurons and intelligence, across 13.8 billion years. Interactive modules where you can experiment first-hand with matter, energy and life.
The Geological Wall
A set of large sections of real rock —tens of tonnes of stone— showing the planet’s geology and how the different strata and landforms were created. A visual and spectacular introduction to earth sciences.
The 3D Planetarium
One of the great attractions: a digital planetarium projecting onto a dome, with 3D imaging and surround sound, with sessions on the universe, galaxies and black holes. There are sessions for the general public and others specifically for younger children (like the Bubble Planetarium). Planetarium entry usually costs extra on top of general admission.
The Antarctic Base and children’s spaces
The Antarctic Base recreates scientific work at the South Pole with National Geographic images. And for little ones, spaces like “Toca Toca” (getting to know animals and plants by touch) or Creactivity invite children to think with their hands. The museum also runs workshops, science escape rooms and a major temporary exhibition that changes every year.
