A baldachin, or baldaquin (Italian: baldacchino or baldachino), is a canopy of state 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. A cloth of honour is a simpler cloth hanging vertically behind the throne, which may be combined with a canopy.
