Mission style home decor is a type of interior design style that was popularized in the late 19th and early 20th centuries. It is characterized by simple, clean lines and an emphasis on functionality. The style originated in Spain, and was later adopted by the Mission San Gabriel in California, where it became known as the Mission Revival style. It is a popular choice for modern homes, as it provides a timeless, classic look that is both functional and aesthetically pleasing.
