Royal Palace - Chinese Room Palazzo Reale Gabinetto-Cinese-room was designed by Benedetto Alfieri, Vittorio Amedeo wedding Duke of Aosta (later elected King Vittorio Amedeo III) Maria Antonia Ferdinanda Borbone Spain in 1750
The balroom of the Catherine Palace, Tsarskoe Selo, Russia. Designed by Italian Architect Francesco Bartolomeo Rastrelli - Court Architect to Empress Elizabeth and master of the Russian Rococo/Late Baroque style.
It is reported the word Rococo is a French word meaning pebble. It refers to the small stones & shells commonly used in the this interior design style.This room is very elegant and flamboyant so I think there is some Baroque style here too.
