The unique architectural feature of one of the most prominent forts in Tamil Nadu, i.e. Aranthangi Fort is its construction of wall. Unlike other historical monuments, the walls of Aranthangi Fort was not built with bricks or stones, rather, the large wall spaces are created with mud. Aranthangi Fort does not demonstrate any evidence of encompassing noticeable constructions or fortresses. In other words, there are no more wrecks of any fort or palaces in Aranthangi Fort.
