Zarrab Khan (Zalkhana, Sarrafkhana) caravanserai was a part of the Blue Mosque complex. It had a diamond-shaped enclosed courtyard with 8 entrances. The complex was built in the second half of the 17th century and completed around 1675-1680. The monument was originally used as a mint, but later it was used by merchants. There were 38 shops in the caravanserai.

The Zarrab Khan caravanserai was destroyed in the 1920s.
