Considering the reality here is that we also have a shameful/disgraceful wall, where people die, or where people are prevented from fleeing war, poverty, lack of freedom, like we had to do when we had a dictatorship (1936-1975), this article and video will help you pick up vocabulary to speak about migration and anti-human rights walls and perhaps democracy and human rights if you reverse the meanings!

After reading this, see if you can explain better things about the wall in the south of Spain and share in class!
