Travertine is a type of rock with multiple pores, and its main component is calcium carbonate. Due to the easy dissolution and corrosion of calcium carbonate by water, natural irregular pores are formed on the surface of the travertine stone. The color tone of the travertine stones is mostly beige, with rich texture and clear stripes, giving people a warm and peaceful feeling, often giving buildings a sense of historical sedimentation and unique cultural charm.

Roman column, its basic unit is composed of column and eaves. The column can be divided into three parts: column base, column body and column head.
