The Royal Palace of Caserta (, ) is a former royal residence in Caserta, southern Italy, constructed by the House of Bourbon-Two Sicilies as their main residence as kings of Naples. It is the largest palace erected in Europe during the 18th century. In 1997, the palace was designated a UNESCO World Heritage Site; its nomination described it as "the swan song of the spectacular art of the Baroque, from which it adopted all the features needed to create the illusions of multidirectional space". The Royal Palace of Caserta is the largest former royal residence in the world, over 2 million m3 in volume and covering an area of 47,000 m2 and a floorspace of 138,000 square meters is distributed in the five stories of the building.
