(1869) ' (round-arch style') is a 19th-century historic revival style of architecture popular in the German-speaking lands and the German diaspora. It combines elements of Byzantine, Romanesque, and Renaissance architecture with particular stylistic motifs. It forms a German branch of Romanesque Revival architecture sometimes used in other countries.

==History and description== The style was the deliberate creation of German architects seeking a German national style of architecture, particularly Heinrich Hübsch (1795–1863). It emerged in Germany as a response to and reaction against the neo-Gothic style that had come to the fore in the late 18th and early 19th centuries. By adopting the smooth facade of late antique and medieval church architecture, it aimed to extend and develop the noble simplicity and quiet grandeur of neo-classicism, while moving in a direction more suited to the rise of industrialism and the emergence of German nationalism. Hallmarks of the style, in addition to the rounded arches from which it takes its name, include "eyebrows" over the windows and inverted crenelation under the eaves.
