Protective window for an ornamental window in which the protective window has an outer frame, protective glazing and optionally mullions that protect the ornamental window while maintaining its beauty. The protective window has extension jambs on the frame that hide the structural portions of the building wall and any mullions in the ornamental window so the two windows have an attractive appearance undiminished by the sight of the edges of the building wall or undersides of the mullions between the two windows.
