Did you know that Chapultepec Castle isn’t built on just any hill? One of Mexico City’s most iconic landmarks sits atop an ancient volcano that formed more than 23 million years ago and is now part of one of the capital’s most surprising geological secrets.
The so-called Cerro de Chapultepec is actually of volcanic origin. It is a monogenetic volcano, a category that includes volcanoes that erupt only once in their entire existence. That single eruption occurs when they form, and after that, they remain inactive forever.
The volcano that supports Chapultepec Castle
Although thousands of people visit Chapultepec Forest every week, few know that the land on which Chapultepec Castle stands is one of the oldest in the Valley of Mexico.
According to information shared by the Chapultepec Forest Site Museum, this volcano is more than 23 million years old. It formed long before the human settlements that later gave rise to Mexico City existed.
Over the centuries, this volcanic promontory became a strategic location for various cultures. Later, it became home to Chapultepec Castle, which today preserves a fundamental part of the nation’s history and offers some of the most spectacular views of the city.
