Fuensaldaña Castle construction started in the 13th century, but it is not until the 15th century that the structure acquires today's configuration. It was built by the Vivero family. The family became linked to the region's history when the future Catholic Monarchs got married in their castle.
Inside, the building was shaped as a 'U' around the cortyard, which today has been made into the parliament floor. During the Comunidades war, it was peacefully occupied by the comunero troops. The castle was the General Assembly of Castilla y León.
Inside the keep are four vaulted halls out of ashlar masonry. The keep, like the curtain walls, is also equipped with round towers at its corners, two nice turrets and battlements.

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.
