St Helens Fort was built between 1867 and 1880 as a result of the Royal Commission, in the Solent close in to the Isle of Wight to protect the St Helens Road anchorage, it suffered badly from subsidence which forced many changes to the plans, ending up with 2 10" eighteen ton RML guns to landward and 1 12.5" thirty-eight ton RML to seaward.
The fort is now in private hands and not open to the public.
