The shroffs (money-changers) effected their usurious and currency transactions under the shadow of Taq-i sarrafon.

The baths of the sarrafon, next door with the trading dome, an indispensable item of an urban public center, were sited next to the passage. Exceptional importance was attached to the medicinal and hygienic properties of baths. As Ibn Sina in his "Canon of Medical Science" has described, good baths must have a firm building, moderate temperature, bright light, pure air, roomy and attractively painted dressing-room and pleasant water.
