The term "Spanish Colonial" refers to the period of Spanish rule in the Americas, which began in the late 15th century and lasted until the early 19th century. This era was marked by the establishment of settlements, missions, and trade routes, as well as the spread of Spanish culture, language, and religion, particularly Catholicism. Architecturally, Spanish Colonial style is characterized by features such as stucco walls, red-tiled roofs, and ornate details. This style can be seen in historic buildings across regions like California, Florida, and Mexico, reflecting the influence of Spanish settlers and their adaptation to local environments.
