Balkh was the main city from which the Aryans moved to the other parts of Persia and Hindustan. It remained as a key city for the spread of Aryan Civilization for several centuries.
Balkh had a major role in the development of Persian language and literature. The early works of Persian literature were written by the poets and writers who were originally from Balkh.
Many famous Persian poets came from Balkh.
A project of modernization was undertaken in 1934, in which eight streets were laid out, housing and bazaars built. Modern Balkh is a center of the cotton industry, of the skins known commonly the West as "Persian lamb", and for agricultural produce like almonds and melons. Numerous places of interest are to be seen today aside from the ancient ruins and fortifications:
* The madrasa of Sayed Subhan Quli Khan.
* Bala-Hesar, the shrine and mosque of Khwaja Nasr Parsa.
* The tomb of the poetess Rabia Balkhi.
* The Nine Domes Mosque (Masjid Now Gumbad). This exquisitely ornamented mosque, also referred to as Haji Piyada, is the earliest Islamic monument yet identified in Afghanistan.
* Tap-e Rustam and Takht-e Rustam
