Ancient indoor ground covering refers to the various materials and techniques used in ancient times to cover floors within buildings. These could include materials like stone, brick, wood, clay, and later on, ceramic tiles. Different cultures and regions had their own preferences and methods for floor construction, reflecting local resources, climate, and architectural styles. For example, in ancient Egypt, the floors were often made of mud or lime, while in China, wood was a popular choice, especially for palaces and temples. The study of ancient ground coverings provides insight into the lifestyles, social status, and cultural values of past societies.
