Colonial cities were urban areas established by European powers during the age of exploration and colonization, primarily from the 15th to the 19th centuries. These cities often served as administrative, economic, and cultural centers for the colonizers, featuring architecture and layouts influenced by European styles. Examples include Mexico City, Havana, and Quebec City. The design of colonial cities typically included a central plaza, government buildings, and religious institutions, reflecting the power dynamics of the time. Many of these cities still retain their colonial heritage, showcasing a blend of indigenous and European influences in their culture and architecture.
