Today marked an important milestone in the development of Royal Caribbean’s newest class of ships, Quantum class, with Anthem of the Seas receiving its first block as the keel was lowered into place.

The keel-laying signifies the beginning of the ship's physical construction. During the ceremony, a 620-ton block measuring 59 feet by 121 feet (18 x 23 meters) was lifted into the building dock with an 800-ton crane.
