Portière

A portière (French pronunciation: [pɔʁtjɛʁ] ⓘ) is a hanging curtain placed over a door or over the doorless entrance to a room.

[1] Like so many other domestic plenishings, it reached England by way of France, where it appears to have been originally called rideau de Porte (literally, "door curtain").

Common in wealthier households during the Victorian era, it is still occasionally used either as an ornament or as a means of mitigating draughts.

It is usually of some heavy material, such as velvet, brocade, or plush, and is often fixed upon a brass arm, moving in a socket with the opening and closing of the door.

[2] Rising portières come in different configurations to seal the curtain against different door surrounds.
