Colonial-era buildings are structures that were constructed during the period of European colonization, primarily from the 16th to the 19th centuries. These buildings often reflect the architectural styles and materials of the colonizing country, such as Spanish, British, or French influences. Common features include symmetrical designs, large windows, and decorative elements like columns and arches. Many colonial-era buildings served important functions, such as homes, government offices, and places of worship. They can be found in various regions around the world, including North America, South America, and Asia. Today, these structures are often preserved as historical landmarks, showcasing the cultural heritage of their respective areas.
