The Palatine Hill is the centremost of the Seven Hills of Rome and is one of the most ancient parts of the city. It stands 40 metres above the Roman Forum, looking down upon it on one side, and upon the Circus Maximus on the other. From the time of Augustus Imperial palaces were built here and hence it became the etymological origin of the word palace and its cognates in other languages (Italian palazzo, French palais, German Palast).
According to Roman mythology, the Palatine Hill was the location of the cave, known as the Lupercal, where Romulus and Remus were found by the she-wolf Lupa that kept them alive. Another legend occuring on the Palatine is Hercules' defeat of Cacus after the monster had stolen some cattle. Hercules struck Cacus with his characteristic club so hard that it formed a cleft on the southeast corner of the hill, where later a staircase bearing the name of Cacus was constructed.
Rome has its origins on the Palatine. Excavations show that people have lived in the area since the 10th century BC. The Palatine Hill was also the site of the ancient festival of the Lupercalia. Many affluent Romans of the Republican period (c.509 BC-44 BC) had their residences there.
From the start of the Empire (27 BC) Augustus built his palace there and the hill gradually became the exclusive domain of emperors; the ruins of the palaces of at least Augustus (27 BC-14 AD), Tiberius (14-37 AD) and Domitian (81-96 AD) can still be seen. Augustus also built a temple to Apollo here. The great fire of 64 AD destroyed Nero's palace, but he replaced it by 69 AD with the even larger Domus Aurea over which was built Domitian's Palace
The Palatine Hill is an archaeological site open to the public. The Palace of Domitian which dominates the site and looks out over the Circus Maximus was rebuilt largely during the reign of Domitian over earlier buildings of Nero.
The House of 'Livia', the wife of Augustus, is conventially attributed to her based only on the generic name on a clay pipe and circumstantial factors such as proximity to the House of Augustus. The building is located near the Temple of Magna Mater at the western end of the hill, on a lower terrace from the temple. It is notable for its beautiful frescoes.
The House of Tiberius is located next to the Temple of Cybele, on the platform built by Nero and in the current Farnese Gardens.
There are also remains of other temples and palaces on the Palatine Hill.
References:The Roman Theatre of Mérida is a construction promoted by the consul Vipsanius Agrippa in the Roman city of Emerita Augusta, capital of Lusitania (current Mérida). It was constructed in the years 16 to 15 BCE. One of the most famous and visited landmarks in Spain, the Roman Theatre of Mérida is regarded as a Spanish cultural icon and was chosen as one of the 12 Treasures of Spain.
The theatre has undergone several renovations, notably at the end of the 1st century or early 2nd century CE (possibly during the reign of Emperor Trajan), when the current facade of the scaenae frons was erected, and another in the time of Constantine I (between 330 and 340), which introduced new decorative-architectural elements and a walkway around the monument. Following the theatre"s abandonment in Late Antiquity, it was slowly covered with earth, with only the upper tiers of seats (summa cavea) remaining visible.
