Monsanto e Idanha-a-Velha is a civil parish in the municipality of Idanha-a-Nova, Portugal. Thanks to its fine collection of ruins, the village of Idanha-a-Velha has some of the country's most important archaeological sites. It stands in a place where a Roman city once lay, the capital of Civitas Igaeditanorum (1st century BC) and later the episcopal seat during occupation by the Suebi and Visigoths.
It was occupied by Muslims in the 8th century and taken back by Christians in the 12th century. It was donated to the Knights Templar in the 13th century and still has traces of different ages that attest to permanent occupation by various civilisations. Perched on a hilltop that oversees all the surrounding horizons, the village of Monsanto has a unique charm that has earned it two titles in the 20th century – the Most Portuguese Village in Portugal in 1938, a title awarded by the Portuguese Secretariat for Propaganda under the Estado Novo regime, and Historical Village in 1995.
Monsanto is one of the region's main tourist attractions and offers visitors a unique experience. It was granted charters by King Afonso Henriques, King Sancho I, King Sancho II and King Manuel. The oldest part is also the highest point, where the Knights Templar built a wall with the donjon.
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.
