Lahore the cultural metropolis of Pakistan and Sultanate of Mughal Empire. The origin of Lahore is obscure and nothing is known about it before 1021AD when Mahmud of Ghazna conquered it. Lahore attained magnificence during the Mughal rule from 1526 to 1721 AD. Lahore was ruled from 1767 to 1846 AD by Sikhs. During the British rule from 1849 to 1947 AD, building and roads were greatly multiplied and the city improved much. The Karakorum Highway also known as the 8th wonder of the world with its unbelievable work done by the Pakistan and Chinese. It took 20 years to complete the KKH, the road winds 800 formidable and majestic miles from Kashgar in western China almost to the Pakistan capital Islamabad. The KKH took 20 years (1960-1980) to complete but the human price paid was considerable. It is supposed that one person died for every one kilometer. Baltistan is home to approximately 400,000 people, whose history and culture stretches back to early Tibetan Buddhist origins. This heritage is still evident in much of the local traditions, architecture and language of the area, offering visitors a rich cultural experience unique in Pakistan.  Here, the magnificent Karakoram and Himalayan ranges meet - an intersection which results in the most extensively glaciated high mountain terrain on the planet. This includes seven of the world's 25 highest peaks, four of which exceed 8000m, including K-2, the second highest mountain peak in the world at 8611m.
