Relics of the Buddhist era dating back to the 8th century can be found here along with burnt diyas and trees with amulets tied to them. Shah Allah Ditta caves are located on the route leading towards Khanpur. These caves are next to the shrine and tomb of Shah Allah Ditta. 2,400-year-old Buddhist era murals of Buddha appear on the walls of caves at Shah Allah Ditta. Archaeological evidence indicates that the caves and the platform-like formations surrounding the area were first used for meditation by Buddhist monks and later by Hindu sadhus before Muslim ascetics took over during the Mughal period. Marked on the ground close to the caves the location where Alexander arrived and was received by Raja Ambi, King of Taxila. The road next to the caves that leads to the main top of the mountain, Shah Allah Ditta road, is said to be built on the exact path followed by Pashtun emperor Sher Shah Suri during his visit. Moving up the mountain from the caves, there is a stepwell called Losar Baoli and a mosque built by Shahāb-ud-Din Ghori. The mosque has broken walls and the road leading to it is dilapidated.
