"This massive building in Chapultepec Park is among the city's most famed museums, second only to perhaps the Museo Frida Kahlo . Though the late Mexican architect Pedro Ramírez Vázquez designed it in 1964, the mammoth building still looks as avant-garde today as it did then. (How exactly does that giant concrete slab float above a pond?) The museum holds the world's largest collection of ancient Mexican artifacts. Some of the most iconic Mesoamerican artifacts discovered to date can be found across 23 rooms. If you want to understand Mexico's history, then a visit here is a must." - Susannah Rigg
