In the heart of Mexico City's historic center lies the Hospital de Jesús, a facility that is more than just a medical institution—it is a living relic of history. Founded by the Spanish conquistador Hernán Cortés in 1524, this hospital has the distinction of being the oldest continuously operating medical center in the Americas. For over 500 years, it has not only provided care but also witnessed the evolution of a nation, from colonial rule to modern times.
