Buddhist stupas are dome-shaped structures that serve as important religious monuments in Buddhism. They are typically built to house relics, such as the remains of Buddha or other revered figures, and are often used as places for meditation and worship. Stupas symbolize the path to enlightenment and are designed to represent the universe in a physical form. These structures vary in size and design, often featuring a circular base, a dome, and a spire at the top. Stupas are commonly adorned with intricate carvings and paintings that depict various aspects of Buddhist teachings and stories. They can be found in many countries where Buddhism is practiced, including Nepal, India, and Thailand.
