The Citânia de Santa Luzia (also known as the Old City of Santa Luzia) is an archaeological site of the Castro culture. Its construction dates from the Iron Age, and it shows evidence of occupation during the Roman period. The Castro was first dug in 1876 by Joaquim Possidonio Narciso da Silva. Only about one third of the structures have been dug, with the remaining part being under or destroyed during the construction of the nearby hotel (1900 - c. 1910), church (1904 - 1943), and respective roads. The site also included a possibly medieval chapel dedicated to Saint Lucy which persisted, after some reconstructions, until 1926 when it was destroyed to give way to the Saint Lucy Church of Miguel Ventura Terra.
The Citânia was constructed on the top of the Santa Luzia hill, overseeing the Lima River's delta and is protected by three lines of walls, towers, and two moats. The innermost walls (1.20 to 1.25 in thickness) enclose a 30m by 20m area that contains a single circular house and its only entrance faces West.
Ruins of approximately 74 houses have been found. Most of them have circular foundations or elliptical, and few are rectangular. The houses are found within small, walled neighborhoods.
The findings of the Citânia de Santa Luzia include multiple ceramics of the Castro, Roman, and Visigothic eras.
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.
