Horse Sand Fort is one of the Solent Forts recommended by the Royal Commission in 1860.  It was built between 1865 and 1880.  It cost some £424,694, a huge amount of money at that time.  It has two floors with armour plate shielding the guns.  The magazines were in the basement under the sea level.

The original armament was intended to be forty five 10-inch RML guns and forty four 12.5-inch RML guns on the two gun decks.  There was plans for five turrets on the roof, each holding two 12.5-inch RML guns.  These turrets were never built.  It is doubtful the Fort was ever fully armed and by 1882 alternate gun emplacements mounted a 12-pdr QF guns, thus having the heavy gun emplacement.

In 1908 a submerged concrete wall was built under the sea running towards Southsea Castle.  There was also a short leg running towards No Man’s Land Fort.  This barrier was to deter larger vessels from running past the Fort, in effect a submerged boom defence.

During World War 2, a pair of 6-inch BL guns were mounted on the roof of Horse Sand Fort.
