Burning of Teotihuacan
The heart of the Americas' largest city is burned

Around 550 the ceremonial centre of Teotihuacan, a city of up to 100,000 people, went up in flames: the temples and elite palaces on the Avenue of the Dead were deliberately set on fire, perhaps during an uprising. The city declined rapidly afterwards.
