Formerly the Town Hall, the Royal Palace serves as the King’s residence when he’s in the city. Its construction was a monumental task when started in 1648 and required the sinking of 13,659 piles to support the mammoth structure. Based upon the architecture of ancient Rome, the exterior is strictly classical, while the interior is magnificently furnished, its apartments decorated with a wealth of reliefs, ornamentation, marble sculptures, and friezes, along with ceiling-paintings by Ferdinand Bol and Govert Flinck, pupils of Rembrandt.

Other highlights include one of the finest furniture collections in the world; the City Treasurer’s room with its marble fireplace and ceiling paintings by Cornelius Holsteyn; and the Hall of the Aldermen, also containing paintings by Bol and Flinck. The largest and most important room is the Council Hall, sumptuously decorated and one of the most beautiful staterooms in Europe. (English language guided tours are available.)
