The piece, installed on the patio in front of the World Chess Hall of Fame in St. Louis by the Chess Club and Scholastic Center of St. Louis, was formed by R.G. Ross Construction, The (St. Louis) Post-Dispatch reported Monday.
"This piece serves as a monument to the chess culture we are creating in St. Louis," club spokesman Mike Wilmering said.
Wilmering said the piece, which was unveiled Monday to commemorate the Tuesday start of the 2012 U.S. Chess Championships, which has been hosted by the club since 2009, was certified by Guinness World Records as the largest on the globe. The previous record holder, a 13.1-foot-high king, was built by Mats Allanson in Sweden in 2003.
