OREANDA-NEWS. August 07, 2015. With officials from the U.S Department of the Interior, National Park Service and Michigan Historic Preservation Office on hand, General Motors  today unveiled a 5-foot-tall, 1,200-pound bethel white granite marker of its Technical Center’s selection as a National Historic Landmark.

The National Park Service selected the campus for the honor because it possesses national significance as one of the most important works of famed architect Eero Saarinen.

The dedication of the marker, which required a crane and several people to guide it into place, also was attended by Executive Vice President of Global Product Development, Purchasing and Supply Chain Mark Reuss and Vice President of GM Global Design Ed Welburn.

“When the GM Tech Center was dedicated in 1956, it was the pinnacle of engineering, design and advance technology,” Reuss said. “We recently announced a \\$1 billion investment that will bring new construction, significant renovation and 2,600 new jobs to the campus,” he said. The expansion of the Tech Center will continue his original design style.
