Answer: These are parts of architectural structures
Notes: Ashoka stone pillars were meant to spread his Dhamma (not the part of architectural structure.) The pillars of Ashoka are a series of columns dispersed throughout the Indian subcontinent, erected or at least inscribed with edicts by the Mauryan Emperor Ashoka during his reign from c. 268 to 232 BC. The pillars of Ashoka are among the earliest known stone sculptural remains from India.
