Tower 65 was auctioned off on June 28, 1910, along with Tower 64. 65 had 7 acres of land with it, part of which the War Department had refused to hire out to the caretaker of the nearby isolation hospital in 1898, to use as a garden. He was also prevented from keeping a boat on the land. Both 64 and 65 still had their cannon mounted at this time.
The tower was said to be safe in 1873, but being built below today's high tide mark, was consequently undermined by the sea in 1933 whilst being lived in by a family.
Various photographs exist showing the cracks becoming wider, including one taken just ten minutes before the entire seawall of the tower crashed onto the beach in front of the photographer.
The tower was washed away over the years, blocks of masonry being visible until being finally covered by the building of the Sovereign Harbour in the early 1990's.
