The lower and more easterly of two caves. A climb up to a single passage with an alcove on the right and which becomes too tight with a narrow rift in the roof.
John Thorp found a polished stone (ophite) in the floor in 1989. Resembling the polished stones axes of Chalcolithic age, it may be a unique find in Cantabria. A line diagram is to be found here and here (from Martínez Velasco Antxoka, 2001)
Further finds have included human bones, pointing to a funerary deposit. Ruiz Cobo Jesús and Smith Peter et al, 2001 discusses the site archaeology and Martínez Velasco Antxoka, 2001 reviews the three ground stone artefacts found in Matienzo.
The site is typical of a Bronze Age burial - a small entrance with the remains placed not far inside the cave (Smith P, Corrin J & Ruiz Cobo J, 2008).
On a visit in 2012, a human finger bone and burnt bones of cow and deer were identified along with bird and other small bones. A piece of red ochre (ruddle) was seen.
