The Qaysariyyah of Kashan was a luxurious bazaar built during the Safavid period and gradually forgotten by the end of the Qajar period. However, an important area within the Kashan bazaar is known as Qaysariyyah. The aim of the present research is to examine the process of gaining importance of the immediate surrounding area of Qaysariyyah bazaar in the second half of the Qajar period and to identify the new definition that the Qaysariyyah area finds in the city. For this purpose, using a historical approach and employing primary sources, the characteristics and functions of the spaces within the area and the activities of individuals associated with them were examined, and the position of these spaces in the city was determined. The results of this research show that although the Qaysariyyah Bazaar of Kashan did not possess its former grandeur in the Qajar period, the location of the chaharsu of the Qaysariyyah bazaar, at the intersection of two main arteries of the city of Kashan, caused its immediate surrounding area to become increasingly important. In the second half of the Qajar period, the Miyanchal Madrasa was transformed into a religious, ritual and social center, which was administered by prominent clerics from a single family. With the construction of three timchehs, the area was transformed into an important commercial center, especially for the exchange of textiles. The madrasa and the timchehs opened onto the Miyanchal Bazaar and the Bazzazan Bazaar; therefore, these arcades were larger and more orderly than the others. The junction of these two arcades, in the south of the Qaysariyyah bazaar, was so crowded that three inscriptions, containing royal decrees and governmental orders, were mounted on the wall of the Miyanchal Bazaar so as to be in public view.
