What type of goods was San Nicolas centered around with its specialized streets?

San Nicolas was historically recognized as a district known primarily for its specialization in the production and trade of specific goods. The area thrived particularly due to its focus on ceramics and soaps, making it a hub for these products. The development of specialized streets indicated a well-defined market, where artisans and merchants concentrated their efforts on these items, catering to both local demand and potential export.

The historical context reflects that cities and districts often developed certain economic activities, which defined their character and led to the establishment of trade routes and communities centered around specific crafts or products. In the case of San Nicolas, the combination of ceramics and soaps created a unique identity and established a strong local economy dependent on these goods.
