The mausoleum was built in 1943 CE, after Hassan Modarres' death in 1937, who was poisoned and then died of suffocation.[2][3] After the exile of Reza Shah Pahlavi, a new tombstone for Hassan Modarres was erected over his grave by locals in an act of honour. A building was eventually built over the grave.[4][3] Following the Iranian revolution, the new Supreme Leader of Iran, Ruhollah Khomeini, restored the mausoleum, and gave it an extensive rebuild.[4][3]
Architecture
The mausoleum was formerly a small building located in the middle of a large garden, which does not exist anymore after the expansion and reconstructions.[4][3] The present mausoleum was built in the Safavid architectural style.[4][3] It has four iwans, one on each side, and the mausoleum is topped by a large turquoise dome. Next to the mausoleum is the library of Hassan Modarres.[4][3]
The grave of Hassan Modarres is located underneath the dome of the mausoleum.[3][4]
