The Gardens of Babur: The first spot for the Truth Booth.

Built in 1528 for Babur, the first Mughal emperor, the gardens are the most popular destination for the people of Kabul to picnic and spend the day.* The park was rebuilt to original specifications of Babur during 2002-2004 who wanted to make a "theater of heaven." His marble tomb resides at the top of the terraces too.
*Awesome Afghan snackbars in there too.
