Today, the urban form of Los Angeles is characterized by 20th-century sprawl and extensive automotive infrastructure. However, the physical reality of the city's original core reveals a more complex history that is deeply rooted in Hispanic heritage. In fact, Los Angeles did not originate from the standardized American land system that defines most of the United States' territory. Instead, it is a product of the Spanish urban tradition in the Americas, which followed a structure repeated across major cities on the continent. The intersection of these systems created a layered urban geometry and history that remains visible in the city's contemporary street patterns.
When Los Angeles was founded in 1781 as a pueblo by Felipe de Neve, it was an outpost of the Viceroyalty of New Spain. Viceroyalties were political divisions of the Spanish territories in America, and by the late 18th century, New Spain was vast. It stretched from southern Costa Rica, all the way north to Alta California, bordering the east at the Mississippi River and the newly independent United States of America. At this time, Mexico City functioned as the primary administrative and economic hub, leaving frontier regions like Alta California to rely on a specific triad of settlements: missions (religious), presidios (military), and pueblos (civilian).
