iCosmoCaixa is the science museum of the "la Caixa" Foundation, set in a Modernista building at the foot of Tibidabo; founded in 1981, it was rebuilt and reopened under its current name in 2004. Its Universe Room, winner of the 2021 Kenneth Hudson Award at the European Museum of the Year Awards, runs from the Big Bang to the frontiers of knowledge. It takes in the Flooded Forest, a piece of Amazon rainforest home to more than a hundred species, and the Geological Wall of seven giant rock sections. Temporary exhibitions and a planetarium complete the visit.
The original laboratory of Spain's Juan Carlos I Antarctic base, with large-format National Geographic photos of polar wildlife and the Amundsen, Scott and Shackleton expeditions.
A 900-metre fossil trail through the museum tracing 27 milestones in the evolution of life, from the first multicellular organisms to hominids.
A 24-metre wall of seven huge real rock sections from different places, each showing a geological process that has shaped the Earth.

A living piece of Amazon rainforest with over a hundred species, seen from underground, underwater and the canopy. Tropical rain falls every 15 minutes.
