Castle of the Dukes of Alba was founded in the 12th century when King Ferdinand II of León ordered to build a simple watchtower. In the 13th century, King Sancho IV of Castile converted the primitive tower into a castle. It was devastated by the battles of the time of King Henry IV of Castile but later rebuilt and converted it into a private palace.
In its interior you can visit several rooms, such as the one that houses the mural paintings of the Battle of Mühlberg.
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.
