窟厂【英】

grotto yard

定义

洞窟前室古代俗名。“厂”意即露舍或无壁屋；莫高窟洞窟前室无前壁，故名。

It is a common term for the front chamber of the grotto in ancient times. The word “yard” in this context in Chinese means an exposed shelter or a house without walls. It is called the grotto yard because the front chamber of a cave of the Mogao Grottoes has no front wall.
