Hola Calibasco,
Yes, when I was a young girl, a few years ago,
I read Cervantes story and was fascinated about what happened there and read other accounts. I have searched the web both here and via Spanish search engines and have not found many historical web sites about Numancia. Not like Italica which has many nice graphic sites to see on the web.
Regardless, I agree with you knowing what took place is enough for me to want to go there and stand in the same area. I am fascinated by that kind of stuff.
I was thinking of visiting Northeast Spain, going from Madrid to Leon to Oviedo, to Santander, to Bilbao and end in San Sebastian where I have a good friend that I have not seen in many years.
Then going down to Soria and back to Madrid. I don't know if this is too much to cover in fifteen days.
But if I can I have to see Numancia!
