The fort is now in private hands and not open to the public. It was offered for sale in 2003. Any private resident would not have any access to local authority services, although it has its own artesian well.

Periodically (often in August) on one of the lowest tides of the year, there is a mass walk from St. Helen's beach out to the fort and back. At this day the causeway appears from the sea upon which the original materials were carried out from the shore at St Helen's Old Church, where there was formerly a quarry. Access is from this point, but also along the spit from Bembridge.
It has become traditional to hold a barbecue on the beach thereafter. This event is entirely spontaneous but safety boat services are provided by local yacht clubs.

 and No Man's Land Fort.
The Solent Forts- often known as "Palmerston's Follies" were built in response to a French invasion scare under Louis Napoleon III. This was due to the doctrines of the "Jeune Ecole" of French naval thinking, which emphasised attacking ports with small craft, instead of fleet action, but was also backed by the first ironclad battleship. This came to nothing with the defeat of France by Prussia in 1870-71.

The forts were later used for defence in the World Wars, although the heavier armaments proved unpopular with local householders due to the concussion breaking windows during firing practice.
Subsequently their main useful role has been as navigational lighthouses.
