Neo-Baroque (also: New Baroque or Second Baroque) is the name of a style in architecture, sculpture and, with reservations, in music (overarching musical style term: neoclassicism).
Neo-Baroque, a manifestation of historicism, is assigned to the second half of the 19th century. It began around 1860, but spread mainly after 1880. Napoleon III created the first large neo-baroque buildings in 1857 with the Tuileries and in 1860 with the Paris Opera. In Bavaria, Herrenchiemsee Palace was built, which recreated the Hall of Mirrors at Versailles.
Neo-Baroque was particularly popular for theatre buildings, as the Baroque had brought with it a heyday of all theatrical art forms. In the late phase of Historicism, the previous orientation towards the Renaissance receded into the background and Baroque forms were used for a wide variety of building tasks, sometimes also for villas and other representative residential buildings.
In Austria, its use had "patriotic" connotations, as it echoed the cultural flowering and political expansion of the early 18th century. In its late phase, it coexisted with Art Nouveau, which it partly influenced.
