Escó or Esco is located to the north of the province of Zaragoza and it was in 1960 that most of the area was expropriated (together with those of Ruesta and Tiermas) for the construction of the Yesa reservoir, with which the town began its decline to abandonment. Now it gives us impressive views of the reservoir between the old and dilapidated houses.
