More information : (SZ 6291 9937) Round Tower [NR] (1)

Between 1416 and 1422, £1069.9s.8 1/2 was spent on building a tower `for the safe keeping of the King's ships', and constructing a wharf at `Childrode' (Gosport) as a foundation for a second tower. The intention was to use a raisable chain to close the mouth of the harbour against enemy shipping. The Round Tower had to be protected from the sea by rocks secured by wooden piling. During Elizabeth's reign, every vessel plying between Portsmouth and the Isle of Wight was required to bring one boat-load of stones per annum and `boye them within the pyles of the Round Tower' or pay a 2s fine. (2)

Between 1492 and 1494, £2099.16s.4d was spent on refurbishing the towers and adding a beaked projection to the South of the Round Tower, `the murder-house', to provide raking gunfire along the Tower's Southern approach. (3)

The chain was still in use in 1779. (4)
