The Downtown Guntersville Historic District is a historic district in Guntersville, Alabama. The district includes most of the central business district of Guntersville, as well as some houses. The town was founded in the 1820s as a port on the Tennessee River. Most of the town was destroyed during the Civil War, although the Henry-Jordan House was spared. The business district began to rebuild after the war, and development was spurred in the late 19th and early 20th century by the Nashville, Chattanooga and St. Louis Railway and by manufacturing firms. The opening of Guntersville Dam by the Tennessee Valley Authority in 1939 turned Guntersville into a peninsula, and created tourism and recreation opportunities on the new lake. Many commercial buildings were constructed after World War II until 1964, in contrast to many small-town downtown areas. Popular architectural styles from the time are represented, including elaborately decorated Victorian, simpler commercial brick styles, and post-war streamlined styles. Notable contributing properties in the district are the Albert G. Henry, Jr., House, the Henry-Jordan House, and the Guntersville Post Office, all of which are individually listed on the National Register of Historic Places. The district was listed on the National Register in 2012.

The Albert G. Henry Jr. House is a historic residence in Guntersville, Alabama. It was built in 1895 by Albert G. Henry Jr., a prominent merchant in the town. Henry's grandfather came to Marshall County in 1828, establishing a mercantile business along the Tennessee River. His son, Albert Sr., continued the business, becoming the dominant store in Guntersville by the beginning of the Civil War. After the war, he extended credit to his patrons to help rebuild the area. Albert Jr. followed his father into business, becoming the only millionaire in Alabama in 1880. He built the two-story, Queen Anne-style mansion in 1895, which features a tower, large wraparound front porch, and extensively detailed woodwork. It sits across from the Greek Revival Henry-Jordan House, built by Albert's brother, Pat, in 1877. The house was listed on the National Register of Historic Places in 1989.

The Company E of the 167th Infantry of the Alabama National Guard Armory is a historic building in Guntersville, Alabama. The armory was built in 1936 by the Works Progress Administration. It was one of 36 buildings constructed by the WPA for the Alabama National Guard, however its hilltop location, rough limestone block construction, and two towers flanking the main entry give it a castellated style, rather than the Streamline Moderne style of the other state armories. In 1978, the company was dissolved, and the armory was used as a fire station until 1998.

In 2006 it was renovated into the Guntersville Museum, and sits as the centerpiece of a public park, which includes a library and community theater. The building was listed on the National Register of Historic Places in 2005.
