Although the first objective of a wall was military and defensive, it had other important functions such as tax collection (right of toll), protection against diseases, control of goods or rights of justice.
All this made it the most important symbol of power during the Middle Ages in the region where he was. Therefore, the right to build a wall was a privilege that was granted as a "right of battlement".
The walls, as a defensive element, were strategically built, if possible in the most impregnable places: higher points of a territory or places protected by large slopes or river beds. Its construction can be dated from the second and definitive repopulation of Cuéllar by Alfonso VI in 1085, although they are not documented until 1264. They are finished building and reformed during the XII to XVI centuries, highlighting the works carried out by the II Duke of Alburquerque towards the year 1500.
Declared an Artistic Historical Monument in 1931, the walls of Cuéllar occupy a large part of the Historic Site of the Villa. Its location in the highest part of the municipality provides a privileged situation for surveillance and defense, highlighting on the whole the Castle - Palace of the Dukes of Alburquerque, beginning and end of them. But, apart from its historical, artistic and monumental value, the walls of Cuellar are a magnificent viewpoint to contemplate a town full of history framed in a sea of pine forests. An image that will cost you forget.
Walk along its adarve, where centuries ago medieval soldiers made the rounds; let yourself be transported to a critical period in the history of Spain, let the walls reveal their shields, loopholes, battlements, merlons and rakes, their secrets and those of Cuellar.
