Chapultepec Castle, perched atop Chapultepec Hill in Mexico City, is a historic site steeped in Mexico's rich past. Originally a summer residence for Spanish viceroys, it has served many purposes: from a military academy to an imperial residence, and now houses the National Museum of History. Its lush gardens and commanding views offer a glimpse into the opulence of bygone eras. While it is already part of the Historic center of Mexico City, a UNESCO World Heritage Site since 1987, Chapultepec Castle is also on the Tentative List of Mexico to become a recognized World Heritage Site in its own right.
