The Museum shall remain closed on public holidays and at weekends in November and December, apart from 3 November and 1 December.
Through its important collections of minerals, rocks and fossils from all the different Spanish regions and former colonies, as well as from sites around the world, the Geominero Museum aims to preserve, research and spread the wealth and diversity of the geological, paleontological and mineralogical heritage.
The historic value of these collections must be added to their scientific importance as they date back to the creation of the Commission for the Geological Map of Spain in 1849. Since then, they have been nourished by works by the IGME (Spanish Geology and Mining Institute) for over 150 years of geological and mining research. However, the building dates back to 1927 when it was opened by King Alfonso XIII on the occasion of the XIV International Geological Congress.
The Geominero Museum still has a lot of activity today. It usually organises educational workshops for children and adults at weekends and during the holidays.
It often goes unnoticed in spite of occupying one of the most unique buildings in the Chamberí district. Work of Francisco Javier de Luque, it is an extraordinary example of an early 20th century scientific museum, with a central hall full of wood carved cabinets and covered with a large zenithal window hanging from a forged iron and lead structure.
