cave was located by J. Caballo and A. García Lorenzo
during an exploration made able on the Castillo Mountain.
From a split, the investigations were able to get in a
cavity from where they could descend to an inferior
gallery, where the paintings are located. The actual
structure of the cave is therefore very different to what
it was when the paintings were made, in which the entry
to the cave would be in the gallery where the decorations
zones can be differenciated. The first one, and the
closest to the primitive entry has got several figures of
animals made by finger engraving. Deeper inside, in a
second room a group of quadrilateral signs made in black linear trace. Finally , the third
zone is a panel with several figures of deers in black paint.
The traditionally atributed chronology
to this group is situated in the III style (between
20000-17000 BP). Recently, direct datations have been
made about some of these figures pigments in the
"Documentación del arte rupestre en el sector
central de la costa cantabrica. Una evaluacion de
tecnicas de trabajo"", leaded by A. Moure
Romanillo,C. González Sainz, V.Cabrera Valdés and F.
Bernardo de Quirós". To be exact two samples of the
lines that appear by the signs and one of the deers. The obtained dates were 13940 ± 140 BP and
15070 ± 140 BP. These results contrast with the
traditionaly admited chronology for this group situated
in the Solutrean. However, if we accept the radiocarbon
dates, it should be delayed until the Magdalenien. On the
other hand, the consideration that the paintings have
been made in a brief period of time goes against the
interval that separates both dates of 14C ,
superior to a millennium.
