Set in a peaceful park of monastery ruins is the impressive 34m Dhamekh Stupa, which marks the spot where the Buddha preached his first sermon. The floral and geometric carvings are 5th century AD, but some of the brickwork dates back as far as 200 BC.
Nearby is the 3rd-century BC Ashoka Pillar , with an edict engraved on it. It once stood 15m tall and had the famous four-lion capital (now in the museum) perched on top of it, but all that remains now are five fragments of its base.
