Daroca - Muralla de Daroca

Daroca is a small town (pop around 2000), which was probably founded by the Moors around 800. After the reconquest of Aragón by Alfonso I de Aragón (aka el Batallador / the Battler) in 1120, the place developed further but was disputed between Aragon and Castile and was in the 13th/14th. Century secured with impressive city fortifications. Pedro IV de Aragón (aka el Ceremonioso / the Ceremonious) granted the place full city rights in 1366. The territorial dispute with Castile only ended with the marriage of the Catholic Kings Isabella I of Castile and Ferdinand II of Aragon in 1469.

The "Wall of Daroca" was first built as a Muslim fortification in the 11th or 12th centuries, the wall expanded under Christian rule. The wall is about 4 kilometers long. It is made of bricks held together with mortar.
About two-thirds of the wall are in poor condition, and parts of it have collapsed.
