The Alhambra was built with its own special type of column, which is not used in any other building. This column has a very fine cylindrical shaft, the base of which has a big concave moulding and is decorated with rings on the top part. The capital is divided into two bodies and the first one, cylindrically shaped, has a very simple decoration and a prism with a rounded-angled base and stylised vegetal forms as decoration.
