Mauryan architecture refers to the architectural style that flourished during the reign of the Maurya Empire in ancient India, particularly from 322 to 185 BCE. This period is marked by the construction of significant structures, including stupas, pillars, and rock-cut caves, which were often built to commemorate the teachings of Buddhism and Jainism. The most famous example is the Sanchi Stupa, known for its intricate carvings and large dome. The Ashoka Pillars, erected by Emperor Ashoka, are another hallmark of Mauryan architecture. These pillars, made of polished sandstone, feature inscriptions that promote moral values and Buddhist teachings. The architectural style is characterized by its grandeur, use of stone, and detailed sculptures, reflecting the cultural and religious ethos of the time.
