High neoclassicism was an international movement. Architects reacted against the excesses and profuse ornament used in Late Baroque architecture. The new "classical" architecture emphasized planar qualities, rather than elaborate sculptural ornament in both the interior and the exterior. Projections and recessions and their effects of light and shade were more flat; sculptural bas-reliefs were flat and tended to be framed by friezes, tablets or panels. This was the first "stripped down" classical architecture, and appeared to be modern in the context of the Revolutionary Period in Europe. At its most elemental, as in the work of Etienne-Louis Boullée, it was highly abstract and geometrically pure.
