Avant-corps

An avant-corps (Italian: avancorpo or risalto, plural risalti, German: Risalit, Polish: ryzalit), a French term literally meaning "fore-body", is a part of a building, such as a porch or pavilion, that juts out from the corps de logis, often taller than other parts of the building.^[1][2] It is common in façades in French Baroque architecture.

Particularly in German architecture, a corner Risalit is where two wings meet at right angles. Baroque three-winged constructions often incorporate a median Risalit in a main hall or a stairwell, such as in Weißenstein Palace and the Roßleben Convent School [de].
