What strikes first time visitors as special or unusual when they arrive in Lahore, Punjab, Pakistan?
I think most important for visitors in lahore is Royal Fort(Shahi Qila). Most visitors must come and see about the glorious past of lahore at the time of Mughal Emperor. There are lots of other things like Royal Mosque, Shalimar Garden(an old garden),Wazir Khan Mosque, Lahore Museum and Food Street Of Lahore are very famous points for tourists.
Mostly people must visit Fortress mall for hangout Dinner and for shopping.
Grand Mosque of Bahria Town
Wazir Khan Mosque
There are tomb of Jahangir Emperor of India and Queen of India Noor Jahan in shahdra near to Lahore city.
