It seems there might be a typo in your question. If you meant "pyramids," they are primarily found in Egypt, with the most famous being the Great Pyramid of Giza. Additionally, pyramids can be found in other parts of the world, including Mexico, where the Mayans and Aztecs built pyramid structures, and in Sudan, where the Nubian pyramids are located. If you meant something else by "pymiads," please clarify!
