The year 943 A.H., mentioned at the end of the inscription above the sanctuary (below the dome), indicates that in the time of Shah Tahmasb I the work of completing the mausoleum was accomplished. On account of the instability of the soil, and the earthquakes that occurred in Shiraz, this building suffered considerable damage, and a part of the dome, which had last been repaired by the late Mirza Abu'l-Hasan Moshiro'l-molk, gave way, and was threatened with collapse, and in spite of repairs, and much reinforcement, which was carried out by the late General Riazi, the former Director of Education in Fars, and subsequently, the threat of dissolution increased daily, until in the year 1950 the dome was taken down by the Fars Department of Education. Then a dome of less weight, with an interior iron structure, was prepared, at the cost of the funds of the mausoleum, and it was placed in position in 1952, and during several succeeding years a covering of brick and enamelled tiling was applied in the shape of the original dome.
