To start with the materials, stone, bricks, and mortar makeup all the main elements of the above-ground structure-the piers and columns, and the arches, vaults, and dome. Substantial but far smaller amounts of iron and timber are found as cramps and ties.
Shifting to the structural use of stone and marble, stone is used chiefly in the piers. It is either limestone or greenstone-a local granite. The blocks vary in depth from 0.45m to 1m. Cut or broken bricks were used where this is necessary for bonding purposes, or where salvaged materials was used in repairs.
