The Battgram district was one of the worst-hit by the October 2005 earthquake, and aftershocks and heavy rains continue to trigger landslides, which have hampered reconstruction efforts and the return of earthquake survivors to their mountain villages from the low altitude tent camps where many spent the winter.

The buildings and gardens are now being carefully restored. Shah Babur, a descendent of Ghengis Khan and grandson of Tamerlane, is credited for founding the great Moghul dynasty which ruled India for two centuries. Babur built the palace and created the gardens on a hill looking over the southern part of Kabul in the 16th century,

The shrine, of particular importance for Afghanistan's Shi'ite Muslims, was first built in the 12th century, destroyed by Genghis Khan, and rebuilt in 1481. The current mosque, considered by some to be one of the most beautiful in Central Asia, is a modern restoration.
