The Aguarales de Valdemilaz, also known as Aguarales de Valpalmas, are a stunning geological landscape located near the town of Valpalmas, in the Cinco Villas region, province of Zaragoza. This site is famous for its unique rock formations, created by water and wind erosion over millions of years. These formations, known as fairy chimneys, are similar to those seen in the Göreme Valley in Cappadocia, Türkiye.

The ruins of the Watchtower tower, probably built between the 9th and 10th centuries, are of Islamic origin. The tower, with a square plan, preserves only three walls, since the south wall collapsed. It is also known as the Four Corners Tower. It is located in a privileged place, on a hill that overlooks the Sotonera reservoir. Its elevated position allowed visual communication with the Tower of San Mitiel or the Bolea castle.

Located on the Gállego River, the Ardisa reservoir is shared by the municipalities of Ardisa and Biscarrués. However, both most of the layout of the dam and all the buildings reviewed are located in the municipality of Biscarrués, which is why they have been included in the catalog of this municipality. The reservoir has an area of 2100 km2, with a total capacity of 5 Hm3 and a useful capacity of 3 Hm3. The dam is made of cyclopean concrete. It presents the type of gravity dam, with a height of 31.14 m and a crest length of 450 m. It has a curved layout and a front arranged in a stepped slope. On the right bank there is a large trapezoidal tank delimited by concrete walls (called a "surface spillway" in the reservoir project) which, through a four-span spillway, connects to a long drainage channel arranged in slope that flows into the river Gállego. The set also consists of several buildings, all of them located on the left bank of the river: the gate house, through which the discharge to the canal that leads water to the Sotonera reservoir is regulated, the dam guard's house , a warehouse and a water tank.

O Aguarales de Valpalmas represent the modeling power of water on rocks. A place that will arouse our curiosity and that of the little ones due to the spectacular nature of its forms. We will find points to observe these geological formations and signs with more information apart from being able to walk among them.

Atalaia which represents an old watchtower just above the Sotonera reservoir, from where you can see the dam as a whole and also the first pre-Pyrenean mountain ranges such as the Sierra de Guara.
