Sears, Roebuck and Company Complex is a complex in Chicago that includes the Sears Merchandise Building Tower and the Sears, Roebuck and Company Administration Building. It was the headquarters and main operations for all parts of the Sears Roebuck Company for almost seven decades. Of the original 41.6-acre (168,000 m2) complex, an area of 16 acres (65,000 m2) was declared a National Historic Landmark in 1978. Relatedly, the current National Historic Landmark status statement questions whether the site, given changes, should be continued as a National Historic Landmark.
