San Felices de los Gallegos Castle has an historical purpose as the frontier stronghold between Portugal and Castile. The enclosure with medieval origins is protected by the castle and the walls which were built in successive periods. The wall, built of stone blocks with adjoining square towers, dates from the 13th century and encircles a spacious bailey. The keep dates from the 15th century, and a third fortified enclosure with bastioned walls dates from the 17th century.
Inside the walls, it is worth noting the parish church (12th-13th centuries) in the transitional Romanesque style (façade and belltower) modified in the Gothic-Renaissance period (16th century), with three naves and a main chapel.Highlights of its civil architecture are buildings such as the Town Hall (16th century) and the Alhóndiga, the former hospitals of Rocamador and La Misericordia, and various noble mansions with their carved coats of arms (16th to 18th centuries), such as the houses known as Los Mayorazgos, El Corregidor and Los señores de Ron.
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.
