The Malek Museum and Library is located at the Mashq Square, which is home to several Qajar era monuments in downtown Tehran. The building and almost all its objects were donated by the Qajar era tradesman, Hossein Malek, to the guardianship of the shrine of Imam Reza (AS) to be converted into a museum and library.

The museum and library was inaugurated in 1927. The library contains 19,000 rare manuscripts and 90,000 printed books.

Among the manuscripts is a copy of Iranian physician and philosopher Avicenna's Kirab al-Qanun fi at-Tibb (The Canon of Medicine). In addition, a copy of the Holy Quran, which is surmised to have been written by Imam Hassan (AS), is kept at the library.

Eighteen works by Qajar era painter, Kamalolmolk, 948 calligraphy works, and 479 miniature paintings and illumination works by eminent Iranian artists are kept in the seven storehouses of the museum.

The storehouses also hold collections of 3000 coins, 11,000 postage stamps, and about 100 Persian carpets and rugs.
