Minat al-Qal'a ('harbour of the fort') is a medieval coastal fort protecting the port known as Ashdod. The fort was built by the Umayyads and later restored by the Crusaders.
The fort was built by the Umayyad Caliph Abd al-Malik ibn Marwan (reign 685–705 CE) before the end of the 7th century on top of Byzantine-era remains. It was in use during the 10th-11th centuries, and was restored and used again by the Crusaders in the late 12th century after sustaining serious damage from the 1033 earthquake. The fort was meant to protect the port from raids by the Byzantine navy, while the port itself was used by the same navy to exchange Muslim prisoners for ransom.
Archaeological excavations show that the fort was restored and reused during the Crusader period. They come to prove what was already known from documents from the era, which indicate that Nicolas de Beroard, a knight of lord Hugh of Ramla, was in charge of the stronghold in 1169. From this period it is known as Castellum Beroart.
The port stops being mentioned during the Ayyubid and Mamluk periods, making it likely that it was destroyed by the Muslims along with the other port cities from the coast of Palestine, due to fears that they might again be used by Crusader invasions from the sea.
The almost rectangular fortress (35x55 meters) was enclosed by a six to seven meters high curtain wall. It has four solid corner towers, and two semicircular ones flanking each of the two huge gates that gave access to the stronghold from the west and east.
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.
