Entering through Gallery A, after 60 or 70 meters, through a tunnel on the right, the first big room of Gallery B is met with. Fairly far away from the entrance which is used nowadays there are various old exits to the exterior which have become blocked with the passage of time. One of them has been made into an opening, but it is not known whether, in the epoch in which this area was decorated, any of these were usable, which would be a help in understanding the point of view which the prehistoric artists would have taken in conceptualizing the zonal arrangement and levels of the room's decoration.[note 5]
