Altamira National Museum and Research Centre

The National Museum and Research Center of Altamira, also known as Altamira Museum, is a center dedicated to the conservation of, research into and the sharing of information about the cave of Altamira in Santillana del Mar, named a World Heritage Site by Unesco.

The museum offers prehistoric technology workshops to visitors, as well as a permanent exhibition called Times of Altamira, which contains objects from Altamira as well as those from other palaeolithic caves of Cantabria such as El Morín, El Juyo and El Rascaño. The New Altamira Cave, or Neocave, is also part of this exhibition: an artificial replica of the original caves, built in order to preserve the originals from damage arising from a massive influx of visitors.
