Some of the finest examples of Ashokan art, are the famous Ashokan pillars that he erected across the country. These columns were works of art, architecture and engineering. The pillar was made out of a single stone which was cut, shaped and polished.

The engineering skill required to make all this possible was indeed substantial, massive blocks of stone had to be hauled in from quarries that were often hundreds of miles away. In some cases they even had to haul the stone to the tops of hills. The fine chiseling and the lustrous polish are examples of well developed skills in this department.

Unfortunately since the building material was essentially wood, not much of this has survived. Excavations have come up with a few structures like a hundred pillar hall.
