The Douglas Historic District includes the commercial area of Douglas, Arizona, a mining company town established in 1901. The dates of the buildings' construction range from 1901 to 1935. The district is bordered on the south by the buildings on G and H Avenues between 15th and 8th Street, and lie only eight blocks from the United States - Mexico border. The District includes architectural styles ranging from Queen Anne to Bungalow to Period Revival. One of the most interesting features is Church Square, which contains four churches in a single block. In 1930 the square was featured in Ripley's Believe It or Not, as the only block in the world which contained four churches: Grace Methodist (built 1902), St. Stephen's Episcopal (built 1903), First Baptist (built 1904), and First Presbyterian (built 1907).
