Imamzamdeh Ja‘far is a historical mausoleum in Borujerd , western Iran . The tomb contains the remains of Abulqasim Ja’far ibn al-Husayn , grandson of the Sh?‘ah Imam Ali ibn Hussayn .
Built in the 11th century AD , Imamzadeh Jafar is one of the few examples of the architecture of the Seljuq and Ilkhanid eras in Iran . A very similar mausoleum is the Tomb of Daniel in Susa , south western Iran . The building is octagonal with a high dome in the center . The height of the conic-shaped dome is 25 meters from the base . The main entrance is in east side and there are two halls decorated with tile work from the Safavid (16th century) and Qajar (19th century) times . The doors and the fringes are decorated by Safavid era intricate decorations . The interior decoration of the building has changed during different times and lastly , it has been covered with millions of small mirrors .
The main gate is in wood , with engraved decorations from Safavid era . Below the ground floor , there is a small room containing the main grave which is not accessible for public .
This shrine is located in the middle of a historical graveyard with many old graves and trees . 30 meters far from the main building there is another historical tomb , known as Do Khaharan ("The Two Sisters") which belongs to two saints .
In March 2006 , a strong earthquake in Borujerd caused extensive damage to the tomb . The mud-brick parts of the building destroyed up to 50% according to the officials and a big hole appeared on the dome .
