The place dominated by the Ucero castle has been inhabited since prehistoric times. The castle is built on the site of an ancient Celtiberian castro. The site was first time mentioned in 1157 when Alfonso VII located the village of Sotos the Suso between Uxama and Ucero and there are documents that indicate that the castle already existed in the 13th century. It is estimated that the important hermit of San Juan de Otero, nowadays destroyed, was ubicated near San Bartolomé, which was a Templarian chapel.

The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
