parclose

A partition that closes off part of a building; especially one that separates an altar or chapel from the rest of a church.

The two eastern bays of this aisle form the Golafre chapel and are inclosed by modern parcloses of oak[…]

It is divided from the north aisle by the great screen, and from the chancel by a parclose of rather poor and spindling work.

An enclosed area, especially one separated from the main body of a building by a screen or partition.

Thenne syr Percyual aspyed that therin was a man or a woman / for the vysage was couerd / thenne he left of his lokyng and herd his seruyse / And whan hit came to the sacrynge / he that lay within that Percloos dressid hym vp and vncouerd his heede / and thenne hym besemed a passynge old man / and he had a crowne of gold vpon his hede "Then Sir Percivale espied that therein was a man or a woman, for the visage was covered; then he left off his looking and heard his service. And when it came to the sacring, he that lay within that parclose dressed him up, and uncovered his head; and then him beseemed a passing old man, and he had a crown of gold upon his head"
