چکیده:

Sheikh Lotfollah Mosque is one of the important mosques in Isfahan located on the east side of Naghshejahan Square. The mosque was built from 1602 to 1606 A.D. by Mohammad Reza Isfahani. The structural balance was damaged after the destruction of the school behind the mosque and later the existing bathroom and Turkish closet. Afterwards, in 1934-1938, the project to construct the buttresses began, due to the thrust movement in the north and north-west side of the mosque. Currently, deformation and movement can be observed, despite the presence of these buttresses which are examined in this research using field studies, a careful examination of the buttresses and vulnerability analysis in the area according to library studies. The results of this study verify the presence of ascending moisture caused by leakage of water and sewage pipes in the area as the main reasons for this damage. Therefore, replacement of pipes, foundation grouting and organizing the area are among the restoration project requirements.

This document which is in the form of a report signed by a finance steward in Isfahan and which has been set under the title of Ministry of Finance, states that: “the repairing of Sheikh Lotfollah Mosque has started as ordered and Shah Square will start soon, and in case of the mosque, the start of the new building will take a few days because they are busy removing the old wall and if you order, in a few days we can hire master Jafar who is an expert in dome construction.

The noteworthy point is that there are currently relatively large cracks in the floor of the hallway, cracks and deformations in the north wall of the building despite the use of an element consistent with the structure (buttresses) and the proper restoration that took place at that time which has shown a good performance in less than a century (Figs 1 to 4).
