In our weeklong trip to the Altamira National Museum and Research Center in April 2024, in collaboration with Asunción Martinez (Educational Department) and Sofía Cuadrado (World Heritage Department), we explored all terrains, human and non-human, inside and around the museum. Having been met right away with the impossibility of entering the original cave, we nevertheless explored the terrain more than any visitor and sought to make sense of it with all our senses. We touched, sniffed, slithered, listened to, and dreamt day and night about the extended Altamira territory, a land with a forest that had been inhabited for so long before the cave paintings garnered international attention. Collected here is a series of sensory experiences that we launched to try to perceive Altamira in its complexity in an attempt to transcend the barriers that exist around the cave itself.
