The Royal Palace of Caserta was once the abode for various Kings of Naples. It is the largest palace in the world and is the finest representation of Baroque art. You can marvel at the various artworks and riches on display at the painted halls of the Royal Apartments.

The title of the "largest palace ever built" is often debated based on whether you measure by floor area or total enclosed grounds, but the Forbidden City in Beijing, China, is widely recognized as the largest palatial complex by area within its walls. Spanning 720,000 square meters (7.7 million square feet), it contains 980 surviving buildings and was the ceremonial heart of Chinese government for 500 years. However, if measuring by the floor area of a single building, the Palace of the Parliament in Bucharest, Romania, is arguably the largest, boasting 365,000 square meters of floor space and an incredible volume. For a modern, currently inhabited royal residence, the Istana Nurul Iman in Brunei holds the Guinness World Record with 2.15 million square feet of floor space, featuring 1,788 rooms. Each of these structures represents the pinnacle of architectural ambition in their respective eras, utilizing vast resources to symbolize the absolute power of the monarchs or states that commissioned them.
