Tallahatchie County Second District Courthouse, County courthouse in Sumner, United States.

The Tallahatchie County Second District Courthouse is a two-story brick building topped by a four-story tower featuring Richardsonian Romanesque details. The structure retains its original early 20th-century appearance, with stone accents and a distinctive tower that dominates the town skyline.

Architect William Sharkey Hull designed and built the brick courthouse in 1910. The building gained national prominence in 1955 when the trial of Emmett Till's accused murderers took place here, making it a significant site in American legal history.

The courthouse was designated part of the Emmett Till and Mamie Till-Mobley National Monument on July 25, 2023. The Emmett Till Interpretive Center, across Main Street from the courthouse, runs guided tours and holds materials on the 1955 trial. The building has been restored to how it looked at the time of the trial.

Visitors can see the building from outside or join guided tours offered by the Emmett Till Interpretive Center across the street, which provides information and context about the site. The best time to visit is when the center is open, as tours and educational resources are available during those hours.

The building was restored to its 1955 appearance for a planned Emmett Till museum, but as of 2018 no museum operates inside; the Emmett Till Interpretive Center stands across the street. A marked driving tour links other sites tied to the murder and trial. On July 25, 2023, the courthouse became part of the Emmett Till and Mamie Till-Mobley National Monument.
