Imamzadeh Saleh is a mausoleum and mosque complex in Tajrish Square in Tehran's Shemiran district. This mausoleum, which is believed to date back to the 13th century, belongs to a son of the seventh Shia Imam Musa ibn Jafar (745-799). The square structure has a tiled dome and strong Ilkhanid era (1256–1335) architectural elements. The shrine has a silver Zarih (lattice cover) and a wooden chest has been placed on top of the Saleh tomb which is believed to date back to the Safavid era (1501 – 1736). The interior of the tomb has tilework decorations, mirror work, fine paintings and stucco reliefs. The mausoleum is a popular pilgrimage site where locals make regular donations of salt and light candles.
