Panteón de Marinos Ilustres (Pantheon of Distinguished Sailors) began construction in 1786, was inaugurated without a roof in 1870, and covered in 1948. Here rest the mortal remains of many Spanish sailors.
From the exterior of the Pantheon of Illustrious Mariños, the sober and imposing doorway in neoclassical style stands out. Inside, the elliptical-shaped vestibule particularly stands out, as well as the church, with three naves and a dome over the transept. The most important feature inside are the tombs of sailors situated in the sections of the side aisles: Gravina, Álava, Valdés, etc.
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.
