National Museum of Rome.  The museum was planned to document ancient Roman history and culture by means of its collections. The Museum’s archaeological heritage is among the richest in the world. The premises of Palazzo Massimo represent the centre of the complex thanks to its four floors, where refined and rare works are displayed: the collection of sculptures and portraits (Bust of Antonino Pio, the Discobolo Lancellotti, Venus of Doidalsas); frescoes and mosaics from Roman villas (Cubicula Leucotea, Livia’s Villa); coin and jewelry collections, jewels and gems from funerary art. The Baths of Diocletian were conceived as an introduction to the knowledge of the origins of Roman history. They house a wide epigraphic section showing the birth of Latin. It is a colossal complex of imperial age and today it houses headquarters of National Museum of Rome. Inside the Baths Michelangelo enclosed a church, the renaissance  basilica S. Maria degli Angeli. Palazzo Altemps, located close to Navona Square, is a severe renaissance dwelling, displaying antique statue collections (Suicide of a Gaul) coming from renowned roman aristocratic families. Crypta Balbi, divided into two sections,  illustrates the transformations and changes of urban scenery and city culture from Roman to Medieval age.
