Kos Minar Lahore
The Kos Minar (Mile Pillars) are a series of milepost markers built during the reigns of Sher Shah Suri and later Mughal emperors. They were originally spaced roughly every three kilometers over major highway routes, particularly the Grand Trunk Road which connected Peshawar in the west to Bengal in the east (a span of over 3,000 kilometers). As the Kos Minars are utilitarian in design, they were not regarded as architecturally significant. Most of them have been torn down, dismantled for their bricks, or otherwise demolished.
