A throne room or throne hall is the room, often rather a hall, in the official residence of the crown, either a palace or a fortified castle, where the throne of a senior figure is set up with elaborate pomp—usually raised, often with steps, and under a canopy, both of which are part of the original notion of the Greek word thronos.

A baldachin, or baldaquin, is a canopy of state typically placed over an altar or throne. It had its beginnings as a cloth canopy, but in other cases it is a sturdy, permanent architectural feature, particularly over high altars in cathedrals, where such a structure is more correctly called a ciborium when it is sufficiently architectural in form. Baldachins are often supported on columns, especially when they are disconnected from an enclosing wall. A cloth of honour is a simpler cloth hanging vertically behind the throne, usually continuing to form a canopy. It can also be used for similar canopies in interior design, for example above beds, and for processional canopies used in formal state ceremonies such as coronations, held up by four or more men with poles attached to the corners of the cloth.
