It is curious Gavin,
thank you very much for your emails,
It's very nice to know we are not crazy.

From very young (9 years old more or
less) I found an old cave on my farm, this farm was
founded by Franciscanos (religious catholic order
at spain), and they made stairs and roof so it could be easily
accessed.

Few weeks ago I found a way to get in through other tunnel, and I
found stairs going Directly down, I got down for at least 45 minutes,
and wondering for the batteries I came back up.

I have very nice feelings when I get in, and wondering how could I
contact its inhabitantas I write you these lines...

I'm glad is interesting for you too Spain, an area with neolitic
settlements at Madrid, the cave goes down more than 2500 yards

through irregular steps, and also goes up as it crosses the sides of
the valley, as it should have another entrance still unfound at the
upper part of one side of the Valley. A old tale names these passages
as 'passage of the monks', as it is beleived that some monks
use to used it to move around.

I am sure that the outter part is made by them, but as soon as the
irregular steps appear the aspect of the cave changes. It is funny as it

looks older but it will last longer... how to explain the endurance and
deep of the feeling.

I wonder if I would have to stay at the cave until my eyes get more
used to the low amount of light and turn off the battery-light. But
this would take more than a weekend, who knows if I could do it.
