The Indian emperor Ashoka (rule: 273—232 BCE) established the Pillars of Ashoka throughout his realm, generally next to Buddhist stupas.
According to Buddhist tradition, Ashoka recovered the relics of the Buddha from the earlier stupas (except from the Ramagrama stupa), and erected 84.000 stupas to distribute the relics across India.
He is also said to have established a chain of hospitals throughout the Mauryan empire by 230 BCE.
One of the edicts of Ashoka reads: "Everywhere King Piyadasi (Ashoka) erected two kinds of hospitals, hospitals for people and hospitals for animals.
The next wave of building, relying on the first examples of true stone architecture, appears with the start of the Classical period (320 BCE-550 CE) and the rise of the Mauryan Empire.
The Jetavana garden was presented to the Buddha by the rich banker Anathapindika, who purchased it for as many gold pieces as would cover the surface of the ground.
The economic reforms of 1991 further bolstered the urban architecture of India as the country became more integrated with the world's economy.
Traditional Vastu Shastra remains influential in India's architecture during the contemporary era.
The architectural decoration is extremely minimal, though there are "narrow pointed niches" inside some buildings.
Most of the art found is in miniature forms like seals, and mainly in terracotta, but there are a very few larger sculptures of figures.
