Location: Courtyard of the Citadel
Description: The sixty-four alternating black and white squares of the giant chessboard are the size of city blocks. The tallest of the sixteen chess pieces are the size of 3-story buildings and weigh 80 tons, and glide toward each other or topple when captured as if moved by a giant invisible hand. Inside a hollow Rook is a spiral staircase of wrought iron leading down to the lower levels. Watching from the Rooks, unseen archers spew a barrage of arrows at intruders seeking this entrance.
