Pyramid of Abusir.
Centuries later, the design and construction of buildings continued to decline. In the 6th century BC, ancient Egyptians began to panic the pyramid and gradually moved to other forms of architecture.
By the 15th dynasty, the Nubia kings were buried in small, low-quality pyramids. From the Middle Kingdom period, the Egyptians only built wooden, brick and brick buildings. Due to poor quality, these works are destroyed, worn over time, there are very few works that still exist today.
