26 Best Things to Do in Mexico City, From Frida Kahlo's Home to Storied Pastry Shops | Condé Nast Traveler

"A distinguished building east of the Zócalo holds (for free!) (to the public!) (in open air!) some of the most stunning Diego Rivera murals in his canon. The building operates as the seat of the federal executive branch of Mexico’s government, so there are office workers milling about and you have to check your bag and show identification before entering the building. But once you turn the corner and come face to face with Rivera’s masterpiece you'll be awestruck. Diego Rivera's famous mural The History of Mexico showcases the Aztec era to the conquest to the Revolution to the development of industry. It's grandiose and captivating, a unique opportunity to learn about Mexico's past. Note that sometimes the building will close at odd hours during the day when there are visiting dignitaries and what not. Make sure and find out when they're open and time your visit. You can't miss this." - Scarlett Lindeman
