Originally a rocky island used as a place of punishment for convicts, Fort Denison was built over and renamed when fortifications were constructed there in the mid-nineteenth century in an attempt to protect the city from seaborne invasion. Though the fort was never used for that purpose, it has collected tidal and meteorological information since it was built.
