Mexico
Temples, cathedral stones and Art Deco halls occupy the same sinking city core.
The Templo Mayor's stones sit a street from the cathedral built partly out of them, and the whole ensemble leans gently as the old lake bed lets it sink. The centre wears every century at once, tilted.
The Centro Histórico layers Mexica archaeology, Spanish colonial streets and modern civic architecture, with Templo Mayor, the Metropolitan Cathedral and the Palacio de Bellas Artes as walkable chapters of one story. Markets, museums and cantinas make it a multi-day district rather than a monument. Its dining rooms carry the city's memory: one famous house has poured coffee since 1912.
