Answer- Painting workshop
The Nigaar Khana refers to the painting workshop founded by Humayun.

A bibliophile of discerning sensitivity, Humayun’s rule began a period of intense patronage for the art of painting and calligraphy. From his period, we get clear visual and textual documents that testify an active interest in building an artistic repertoire and an imperial atelier. This is an indication of Humayun’s artistic taste and helps us form a picture of Humayun as a connoisseur and an aesthete. He founded the Nigaar Khana (painting workshop), which was also a part of his library. Not much is known about the size and composition of Humayun’s workshop in India. However, it is known that he started the project of illustration of Hamza Nama that was continued by his son and successor Akbar.
