About the place

A prominent rocky outcrop stands above central Santiago as both a public park and a historic fortress.

Known anciently as Huelén by indigenous communities, the hill gained its Spanish name under Pedro de Valdivia. Early colonial missionaries gathered on the slopes for prayer during a chickenpox epidemic. Royal engineers later fortified the heights with stone ramparts, ammunition depots, and Fort Hidalgo. The surrounding ground also served as a burial site for religious dissidents denied entry to consecrated churchyards.

Scientific expeditions led by James Melville Gilliss established an astronomical station on the peak to measure solar parallax, leaving instruments that seeded the National Astronomical Observatory. Urban planner Benjamín Vicuña Mackenna later transformed the rocky outcrop into a public park, introducing gas illumination, a hilltop chapel, fountains, and yellow and white facades alongside a regular cannon firing tradition.
