or Second Empire style or Second Empire Baroque
Architectural style developed at the École des Beaux-Arts in Paris.
It enjoyed international dominance in the late 19th century (see Second Empire ) and rapidly became an official style for many of the new public buildings demanded by expanding cities and their national governments. Beaux-Arts buildings are typically massive and have a symmetrical plan with rooms arranged axially, profuse Classicist detail, and pavilions that extend forward at the ends and centre. Among the most admired Beaux-Arts structures is the Paris Opéra .
