The interactive museum Planetario is inaugurated as part of a collaborative project between the Government of Japan, the Ministry of Science, Technology and Environment of Cuba and the Office of the Historian of the City in 2009. In this scientific and cultural center the big bang, the solar system and the galaxy, all that what is related with the birth of our planet and the cosmos, is explained in an impressive way by three dimensional representations and models. The 45-minute guided tour is particularly educative for kids that would imagine the 13.700 million years of the universe during their visit of the rooms spread over four floors.
