Alcalatén Castle, located on San Salvador Mountain in the municipality of Alcora, is an Islamic fortress with medieval architectural reforms, built between the 10th and 13th centuries.
In 1233, after the conquest of Borriana, King James I granted the castle and the title of baron to the Aragonese knight Ximén d'Urrea.
The castle, with a triangular layout, covers an area of 150 square meters. It includes a main enclosure surrounded by a patrol path, with a cistern, as well as both abandoned and inhabited areas.
At the highest point, two walls forming a right angle and topped with battlements are preserved, extending into two towers; one circular to the north and one semicircular to the south. A third tower is known to have existed, though only rubble remains from its demolition in the 15th century. The eastern section is completely destroyed. At the base of the citadel, a rectangular cistern made of mortar and stones remains, measuring approximately 4 by 10 meters. The structure is built with masonry.
The entrance is on the south side, featuring two circular towers, battlements, and a barbican-style wall.
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.
