There aren’t any medieval castles in Afghanistan, and actually very few
historical buildings can be found here. Still, the Bala Hissar near Kabul is one of the oldest fortifications in
the area, dating back to the 5th century.
Also, some ruined palaces built at the start of the 20th century can be
found here, like the Darul Aman Palace.
Because of the current political situation, visiting these ruins is not
advisable for the average tourist. There is work done to preserve these remains, but their
future is uncertain.
