"This massive building in Chapultepec Park is the most well-known museum in Mexico City (second only to the Museo Frida Kahlo). Though it was designed in 1964 by late Mexican architect Pedro Ramírez Vázquez, the mammoth concrete building still looks as avant-garde today as it did then. (How exactly does that giant concrete slab float above a pond?) The architecture is perhaps as impressive as the exhibits; some people come just to see the building. The museum is home to the world's largest collection of ancient Mexican artifacts, spread across 23 rooms. Some of the most iconic Mesoamerican artifacts discovered to date can be found here. If you want to understand Mexico's history, then a visit here is a must." - Scarlett Lindeman
