If you're interested in learning about past civilizations, check out Ethnographic Museum. Study its age-old artifacts and gain an insight into the cultures and traditions of people from long ago.
When you've finished up at this exhibition of human history in Serradilla, why not make your way to Salto Del Gitano, Parque Natural, and Castle of Monfragüe? They're not too far from Ethnographic Museum and also a hit with many tourists.
