The Roman Forum is an archaeological area in Mérida, Spain. It was the main public area of the Roman city of Emerita Augusta, founded in 25 BC by Emperor Augustus. The city had another forum, the Provincial Forum, built in 50 AD. Together with the other archaeological sites of the city, it was inscribed in the UNESCO World Heritage List in 1993.
The most impressive sight in forum is Temple of Diana: Despite its name, wrongly assigned in its discovery, the building was dedicated to the imperial cult. Erected during Augustus' reign with local granite, later it was partly re-used for the palace of the Count of Corbos.
There is also a Temple of Mars, dedicated to the imperial cult, and portico which was built in the 1st century. It consists of a porticoed building with a wall housing several niches intended for statues found at this site. The portico was restored in the 20th century, and the discovered remains are on display at the National Museum of Roman Art.
References:The Villa d'Este is a 16th-century villa in Tivoli, near Rome, famous for its terraced hillside Italian Renaissance garden and especially for its profusion of fountains: the extraordinary system contains fifty-one fountains and nymphaeums, 398 spouts, 364 water jets, 64 waterfalls, and 220 basins, fed by 875 meters of canals, channels and cascades, and all working entirely by the force of gravity, without pumps. It is now an Italian state museum, and is listed as a UNESCO world heritage site.
Tivoli had been a popular summer residence since ancient Roman times due to its altitude, cooler temperatures and its proximity to the Villa Hadriana, the summer residence of the Emperor Hadrian I.
The Villa was commissioned by Cardinal Ippolito II d'Este (1509-1572), second son of Alfonso I d'Este, the Duke of Ferrara and grandson of Pope Alexander VI, along with Lucrezia Borgia.
