It was originally called Huelito o heutrecan by the pre-colonization inhabitants. However, the current name comes from the day in which Pedro de Valdivia conquered the hill, on December 13, 1540. That day celebrates "Santa LucÃa."
Its first use by its missionaries was as a point of worship, or prayer in the years of the chicken pox outbreak (1541).
In 1816, Manuel Olaguer Feliú, the Brigadier of the Royal Engineers, designed and built two forts or castles on Santa LucÃa Hill, one north and the other south of the hill. The forts were built out of stone and lime and could fit eight or twelve cannons each. Besides, Olaguer Feliú drew and built an outbuilding for ammunition depot and to house the garrison.[4]
On one side of the hill, Fort Hidalgo was finished in 1820 as a defensive point. On the other side, the hillside terrain was used as a "cemetery for the dissidents", people who did not follow the then-official Roman Catholic faith, or were considered otherwise unworthy of burial at hallowed grounds. However, the remains buried in the hillside under this fashion were eventually transferred to a secluded section of the General Cemetery, before said cemetery, in turn, was opened to all burials regardless of creed or social condition.
In 1849 James Melville Gilliss led an American naval astronomical expedition to Chile in order to more precisely measure the solar parallax. An observatory was set up on Santa LucÃa Hill and operated by Gilliss. When the expedition ended in September 1852 the observatory and related equipment was sold to the Chilean government and formed the nucleus of the first National Astronomical Observatory.[5]
In 1872 BenjamÃn Vicuña Mackenna decided to conduct a dramatic change to the urban atmosphere of the city of Santiago, among his many works aimed to improve the city, and thus initiated an extensive remodelation of the hill. The works of 1872 consisted of a road which crossed the hill, which at the top accessed a chapel which he also built there, illuminated by the then-novel means of gas. The rest of the hill contains a park with fountains and lookouts. The actual hill is watered by a sophisticated irrigation system. The now iconic yellow and white facade is also a product of Vicuña Mackenna's remodelation.
Vicuña Mackenna was assisted in realizing his designs by the architect Manuel Aldunate, the constructor Enrique Henes, and the stonecutter Andrés Staimbuck.
A few years ago, Santa LucÃa hill received an improvement in its illumination system and protections. Also, Fort Hidalgo was restored and reopened to the public. Traditionally, a cannon shot is fired exactly at noon.
In popular culture
Santa LucÃa Hill is one of the entrances to the abyss in the videogame Abyss Odyssey, the entrance is located in the east part of the Terraza Neptuno.
Santa LucÃa Hill was featured on the second episode of The Amazing Race 7 with the competing teams finishing their leg in Santiago at Terraza Neptuno.[6] The eighth season of the Israeli version of The Amazing Race also finished its sixth leg at Terraza Neptuno.
