// A round medieval knights' tournament tent: a cylindrical cloth wall with vertical stripes in deep red and cream, a conical striped roof with a scalloped hanging trim in gold, a tall pole on top with a blue pennant, and an open triangular front flap tied back showing a dark interior. A heraldic shield (blue with a gold lion) hangs beside the entrance.
