Marfil is a neighborhood in the city of Guanajuato, which is located in the Central Highlands of Mexico at an altitude of 6500 feet.
The area was settled in the middle 16th century and developed as a major silver mining town. When the silver mining became less profitable, the city became a sleepy provincial town and did not participate in major modernization.
Guanajuato was built into a steep valley. As a result most of the streets in the city center are pedestrian and much of the inter city traffic is conducted through a complex system of tunnels.
Because of this geography and history, the city center of Guanajuato has retained the atmosphere and architecture of a Colonial city. It is no longer sleepy. Located in the city is a major university which creates a rich artistic and cultural atmosphere. Guanajuato, along with its neighbors Dolores Hidalgo and San Miguel de Allende, is in the historic heartland of Mexico.
