Remains of monumental stone architecture with a strong Achaemenid and Greek influence can be seen through numerous artifacts recovered from Pataliputra, such as the Pataliputra capital.
This cross-fertilization between different art streams converging on the subcontinent produced new forms that, while retaining the essence of the past, succeeded in the integrating selected elements of the new influences.
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.
Particularly, the Jetavana at Sravasti, shows the three favourite residences of the Buddha: the Gandhakuti, the Kosambakuti and the Karorikuti, with the throne of the Buddha in the front of each.
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.
In effect, many stupas are thought to date originally from the time of Ashoka, such as Sanchi or Kesariya, where he also erected pillars with his inscriptions, and possibly Bharhut, Amaravati or Dharmarajika in Gandhara.
Ashoka also built the initial Mahabodhi temple in Bodh Gaya around the Bodhi tree, including masterpieces such as the Diamond throne ("Vajrasana").Numerous donors provided the funds for the building of these caves and left donatory inscriptions, including laity, members of the clergy, government officials, and even foreigners such as Yavanas (Greeks) representing about 8% of all inscriptions.The construction of caves would wane after the 2nd century CE, possibly due to the rise of Mahayana Buddhism and the associated intense architectural and artistic production in Gandhara and Amaravati.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 capital city of Pataliputra was an urban marvel described by the Greek ambassador Megasthenes.The architecture of India is rooted in its history, culture and religion.
