The National Archaeological Museum of Spain was founded in 1867 by a Royal Decree of Isabella II as a depository for numismatic, archaeological, ethnographical and decorative art collections of the Spanish monarchs.
The museum was originally located in the Embajadores district of Madrid. In 1895, it moved to a building designed specifically to house it, a neoclassical design by architect Francisco Jareño, built from 1866 to 1892. In 1968, renovation and extension works considerably increased its area. The remodelled museum concentrates on its core archaeological role, rather than decorative arts.
The collection includes, among others, Prehistoric, Egyptian, Celtic, Iberian, Greek and Roman antiquities and medieval (Visigothic, Islamic Spanish and Christian) objects.
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.
