The Plaza Santo Domingo in the historic center of Mexico City is the southern terminus of ‘The Royal Road of the Interior Land’, a World Heritage Site. As you can see above, some vendors still use traditional market stands on this trade trail first developed by pre-Columbian empires. The whole trail was originally a native trading route for turquoise, obsidian and feathers, and after the Spanish conquest, it was used for military, religious expansion and for silver. From this plaza, the road runs north through San Miguel de Allende, Guanajuato and Zacatecas all the way through El Paso (‘the pass’) to Santa Fe (‘holy faith’). The US section—with the same Spanish name—is a national historic trail.

In the background is the Palace of the Inquisition, which arrived from Spain to punish the son of Hernán Cortés, Martín, who threatened independence in 1566. Public burnings of witches and heretics were common for ~250 years, until Mexican Independence ended the practice in 1820. The ‘palace’ now houses a UNAM medical museum, although there is a small gory museum of the inquisition a few blocks away. Mexico City is the largest and oldest city in North America, and it is well worth visiting to be able to walk in the footsteps of history.
