Talk:Fort San Cristóbal (Spain)

More examples, please
I have written: "The advances in artillery during late nineteenth century forced the military authorities to build this kind of fortifications in order to control mountains and hills close to important towns. Another example of this is the fort San Marcos, near to San Sebastián". I do not remember more examples but it is likely to exist more. If you know, please improve the article.
