Prime Minister Imran Khan will visit to Nandana Fort tomorrow and launch it as heritage site.

In a tweet message today (Saturday), the Prime Minister Office said that the Prime Minister Imran Khan is keen in preservation and conservation of the site and to convert it into an international tourism stop.

The site's archaeological significance dates back to 11th century when famous scholar Abu Rehan Al-Biruni during his stay quantified the circumference of the Earth.

Later, he wrote a famous book about the region and mentioned Nandana as a great center of learning.
