The Plaza of Three Cultures / Plaza de Tres Culturas is remarkable not only for the collision of past and present but the numerous tragedies that have occurred there, starting with Cortez' massacre of the Aztecs followed hundreds of years later by the Army's murder of hundreds of student protesters in 1968 and finally the 1985 earthquake.
We visited on a bright quiet day and there were only a few other tourists but the place was crowded with lessons and, no doubt, ghosts.
