Netley Castle was originally one of three castles built on the order of King Henry VIII to defend Southampton Water from an imminent French attack. Unlike the other two, Calshot Castle and St Andrews Castle [Also known as Hamble Castle or St Andrew's Point Castle. ] , Netley Castle was extensively remodelled in the 19th Century to create an attractive, gothic castle visible from Southampton Water, though all but burying the remains of the original castle. Sadly, Netley Castle is not open to the public but is being developed into flats.
