The Amaravati Stupa in Andhra Pradesh, although originating possibly in earlier times, flourished mainly during the Satavahana period (2nd century BCE to 3rd century CE) and later, making it primarily a post-Mauryan (specifically Satavahana) stupa known for its exquisite carvings. Sarnath and Bairat have significant Mauryan structures, including Ashokan pillars and stupa remains. Nandangadh (Lauriya Nandangarh) is famous for its Ashokan pillar and burial mounds possibly related to Mauryan period.
