The Cotton Exchange Building is a historic building located in downtown Houston. Built in 1884, it is listed on the National Register of Historic Places. The Houston Cotton Exchange and Board of Trade commissioned local architect Eugene Heiner to design a three-story building on Travis Street at the corner of Franklin in Houston. In 1907, the building was remodeled and a fourth floor added. The Houston Cotton Exchange continued to use the building until it moved its operations to a new building several blocks away at Prairie and Caroline in 1924.
