National Geographic under the History Channel has a documentary film on the site where the relics of the Buddha were found. In 1898, an amateur archeologist discovered a vast ancient stupa in Piprahwa, near the Buddha's birth place.
The video is 45 minutes long, so you need to take time to watch this. This year, 2013, Wesak Day is on Friday 24 May. So it is opportune to share this video.
