Salvaterra de Miño has always carried out an important military function because of its strategic location next to the Miño River.
There is hardly anything left of the original 12th century walls that used to protect the castle. The fortress, however, built in the 17th century, still stands, and was refurbished in 2008. As well as many sentry boxes on the walls, other buildings were built such as the Baroque chapel (17th century) of La Virgen da Oliveira and the Casa del Conde house (17th century), with the Doña Urraca caves and double room with a spiral staircase can be found.Inside the fortress, as well as remains of streets, houses and gravestones, we can find the palace or manor house of Doña Urraca, named after the room of Queen Urraca I (1109-1126) during a war with the Countess Teresa of Portugal.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
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.
