The imposing Bala Hisar Fort and its bleak ramparts still appear to monitor movement along the Grand Trunk Rd. Babur first built a fort here in 1526 after capturing Peshawar. It was a royal residence for the Afghan Durrani dynasty before being captured, trashed, and in 1834, rebuilt in mud by the Sikhs (replaced by brick by the British). It's now the headquarters of the Frontier Corps. Access inside is limited, but there's a small museum and great views over the city from the ramparts.
