Schloss Sanssouci, Potsdam: close-up of the dome, cornice and corthinian columns in the white and gold oval Marble Hall (Marmosaal)

NOTES: Sanssouci was the summer palace of Frederick the Great, King of Prussia. Built above a terraced vineyard in 1745-1747, it is essentially a single-storey villa, containing ten principal rooms. The Marble Hall, completed in 1749, was designed as the principal reception room and was used by Frederick as an informal dining room.
