The Ashokan Pillar, essentially erected by Ashoka (249 BC) visited Lumbini and erected an inscribed Ashokan Pillar on the spot of Buddha's birth. The inscription of the pillar (the oldest in Nepal) declares that Ashoka granted Lumbini tax-free status in honor of Buddha’s birth. It is 6m high and half of it is beneath the ground. It is behind the Maya Devi Temple, to the west of the temple. Emperor Ashoka erected many other pillars throughout India. The carved top of the pillar has never been found.
The Buddhist monastery - Its built in the way of the modern Buddhist temples of Nepal but is quite important in the purview of architecture of the walls. The middle hall contains some exquisite murals resembling the medieval periods'.
Lumbini remained neglected for centuries. In 1895, Feuhrer, a famous German archaeologist, discovered the great pillar,further exploration and excavation of the surrounding area revealed the existence of a brick temple and a sandstone sculpture within the temple itself which represents the scenes of Buddha’s birth. On the south of the Maya Devi temple there is the famous sacred bathing pool known as Puskarni. It is believed that Maha Devi took a bath in this pool before the delivery. The temple is built gradually and is composed of many temples, one after the other. It is also found that there is possibility that a Ashoka Stupa existed in the place of temple.
