Foster Observatory on San Cristóbal Hill

A journey to the origins of astronomy in Chile

High on San Cristóbal Hill lies one of the most important scientific and heritage treasures in Santiago: the Manuel Foster Observatory.

Inaugurated in 1903 by the Lick Observatory of the University of California, it was the first modern astronomical observatory installed in the southern hemisphere and marked the start of a long astronomical tradition that today positions Chile as a world power in observing the universe.

Its characteristic white dome and historic refractor telescope have witnessed important scientific research for more than a century.

Located just steps from the Manuel Foster Station of the Santiago Cable Car, this place lets you discover a different side of San Cristóbal Hill, where science, history and heritage come together in one space.

A unique experience to discover the universe

Today, the Manuel Foster Observatory opens its doors on weekends with special guided tours, inviting visitors to learn about its history, tour its facilities and discover how astronomical observations were carried out at the beginning of the 20th century.

During the experience you can enter the historic dome, learn how its telescope works and discover the findings that helped drive astronomy in Chile. All accompanied by spectacular panoramic views of Santiago from one of the highest points of San Cristóbal Hill.

A must-see visit for those who enjoy science, history and the places that have left their mark on the country's development.
