It is a bastion fort with an irregular hexagon shape and seven bastions. This comprised a strong earthen rampart, enhanced with bastions and redoubts. These forts still lacked some of the more modern continental features, such as angled bastions. One of the bastions of the fortress now houses the mini museum Bastionder. Each was placed in charge of one of the 72 bastions of the Madurai fortifications. A moat and numerous bastions were also constructed. It was a single rampart long reinforced by 94 bastions. This cliffside fort has cannons, intact bastions and a courtyard. It consisted of a semi-circular earthwork reinforced with wooden stockade and five bastions. Numerous colonial-era Portuguese cannons are still positioned on top of the bastions. Thereafter, their bodies were hung in gibbets erected at the bastions of Fort Ricolli. The walls would have consisted of towers that were either empty or used as bastions. The town's existing defences were adapted to create ten bastions. There are many cannons of native and European make rusting on the bastions. They are often built from Hesco bastions.
