Answer:
The Pakistani historical cultural interest that I would like to visit is the Historical Monuments at Makli, Thatta. 
I'm fascinated by the site as it is one of the largest funerary in the world as it occupies a space of up to ten kilometres in the city of Thatta. 
Historically, it is said to house over a million tombs that was built in the time period of four hundred years. 
It would be interesting to visit this Pakistani historical interest because I would be able to experience such culture and satisfy my curiosity.
