Rococo architectural style,1came into being in France in the 1920s and was popular in Europe. It was developed on the basis of Baroque architecture, mainly in interior decoration. The basic characteristics of Rococo style are delicate, gorgeous, exquisite, sweet, gentle and complicated. Against the background of the decline of European feudal aristocratic culture, it shows the decadent and flashy aesthetic ideals and thoughts of the declining aristocratic class. They can't stand the seriousness and rationality of classicism and the noise of baroque, and pursue beauty and leisure. The word rococo evolved from French rocaille, which originally meant the shell-shaped pattern in architectural decoration. 1699, architect and decorative artist Marley adopted this curved shell pattern in a large number of decorative designs of the king's residence, hence the name. Rococo style first appeared in the interior decoration of buildings, and later extended to the fields of painting, sculpture, handicrafts and literature.

Rococo architectural style is characterized by bright colors, exquisite decoration, and exquisite and complicated furniture, unlike Baroque style with strong colors and rich decoration. The interior space of Rococo architecture in southern Germany and Austria is very complicated.
