Luigi Vanvitelli, Italian architect and engineer, designed the Palace of Caserta and Royal Palace of Milan (died 1773)

Luigi Vanvitelli, known in Dutch as Lodewijk van Wittel, was an Italian architect and painter. The most prominent 18th-century architect of Italy, he practised a sober classicising academic Late Baroque style that made an easy transition to Neoclassicism.

The Royal Palace of Caserta is a former royal residence in Caserta, Campania, 35 kilometres (22 mi) north of Naples in southern Italy, constructed by the House of Bourbon-Two Sicilies as their main residence as kings of Naples. The complex 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 covering an area of 47,000 m² and a floorspace of 138,000 square metres distributed across five floors.

The Royal Palace of Milan was the seat of government in the Italian city of Milan for many centuries. Today, it serves as a cultural centre and it is home to international art exhibitions.
