The Royal Basilica of San Francisco el Grande is a Roman Catholic church in central Madrid. The main façade faces the Plaza of San Francisco, at the intersection of Bailén, the Gran VÃa de san Francisco, and the Carrera de san Francisco. It forms part of the convent of Jesús y MarÃa of the Franciscan order. The convent was founded in the 13th century at the site of a chapel.
The basilica was designed in a Neoclassic style between 1761 and 1768, based on a design by Francisco Cabezas, developed by Antonio Pló, and completed by Francesco Sabatini. The church contains paintings by Zurbarán and Francisco Goya. The temple once functioned as the National pantheon and enshrined the remains of famous artists and politicians.
The dome is 33 metres in diameter and 58 metres in height; its shape is very similar to the Pantheon's dome, having a more circular shape than the typical domes built in the 18th century.
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.
