Jean II of France, and finished in 1350. It is the tallest tower of the Conciergerie, five levels high, with battlements and a lantern tower at the top; it served as both a watchtower and clock tower. The clock was installed during the reign of Charles VI of France, and was the first public clock in Paris. In 1585 King Henri III of France embellished the clock with a new face, set on a blue background with gold Fleurs-de-lis, and framed by statues of law and justice by sculptor Germain Pilon.

During the reign of Philip IV parts of the hall were sometimes used for the meetings of special commissions appointed by the King to investigate problems in the royal institutions in the French provinces. These parts would be separated from the rest of the hall by partitions or tapestries during the meetings. The hall particularly provided staff and services for the Great Hall, located directly above it on the first floor. The lower hall was connected with upper hall by spiral
