Urban Wall of Frías

It surrounds the entire city of Frias!! The city walls of Frías, more commonly known as the Wall of the Millstone, is located in La Muela. It's very old and it dates back to the 13th century and it's noted that it has three entries where the doors were: the Postigo, the Medina and the Villa. In ancient times it was surrounding the entire city, from the castle to the church, but right now you can only see some of the ruins from the construction of some of the houses and the ruins of the top part. This is also an important place because it was declared a Historic Artistic Monument of Spanish Heritage.
