Why are pillars the excellent examples of Indian architecture? Explain.

pillars are an excellent example of Indian architecture because:

a) These pillars are very beautiful and extremely well-crafted. For example, around thirty pillars were erected across India by Emperor Ashoka. These resembled the trunk of an elephant and were 40 to 50 feet tall. Their smoothness, polish and glitter has withstood the test of time.

b) The pillars are indicative of advances in scientific knowledge. For example, the iron pillar of Delhi and the stone pillar of Belur, Karnataka. The Iron Pillar is corrosion resistant and the stone pillar has stood without support on solid ground, even without digging.
