 from the outer defences over the water to an island called a ravelin, which is in turn linked to the inner defences by another replica bridge, protected with two drawbridges. The ravelin formed a physical barrier to incoming artillery fire aimed at the entrance to the inner defences and could also have directed fire against enemy forces that breached the outer defensive line.

On the south side of the outer defences, facing the river, are the West and East Lines of gun positions. These were built in the 18th century and have been subject to considerable erosion and silting; 12 of the original 14 gun positions on the West Line remain but only one of the East Line has survived. In between the lines is a quay, designed to allow the delivery of supplies from the Thames, and the remains of the tracks from the narrow gauge railway built during the First World War. A sluice gate in the south-west corner managed the water in the moats, and allowed them to be drained completely should the surfaces begin to freeze over in winter and provide an advantage to any attackers. To the west of the outer defences is the World's End pub, originally the local ferry house, dating from 1788.

Inner defences
The inner defences largely follow a pentagonal design, with four defensive bastions positioned around a central parade ground. From the south, the fort is entered through the Water Gate. This two-storeyed gatehouse dates from the late 17th century with a monumental stone facade featuring carved displays of classical and 17th-century weapons; when first built, the now-empty niche at the front probably held a statue of King Charles II. The building originally acted a house for the master gunner. Most of the inside of the fort is taken up by the parade ground, an area covering. The central parade ground was raised to its current height in the 17th and 19th centuries using chalk and dirt, and by the early 20th century much of it was occupied by four large warehouses, since destroyed.

Moving east from the Water Gate, the south-eastern curtain defences and the south-east bastion were rebuilt at the start of the 20th century to hold emplacements for four quick-firing guns and two 6-inch (15 cm) guns, with tunnels linking to an underground magazine. Four artillery pieces, dating from 1898 to 1942, are on display. Facing the parade ground are the officers' quarters,

 On the south side of the outer defences, facing the river, are the West and East Lines of gun position. These were built in the 18th century and have been capable to considerable erosion and silting; 12 of the original 14 gun side on the West Line remain but merely one of the East Line has survived. In between the lines is a quay, designed to allow the delivery of provision from the Thames, and the remains of the tracks from the narrow gauge railway built during the First World War. A sluice gate in the south - west corner managed the water in the moats, and allowed them to be drained completely should the surfaces begin to freeze over in winter and provide an advantage to any attackers. To the west of the out defences is the World's End public house, primitively the local ferry theater, dating from 1788.
