Trial Bay gaol was built to house prisoners who were brought to the area in 1886 to construct a breakwater to make Trial Bay a safe harbour halfway between Sydney and Brisbane. . Then, during World War 1 the gaol was used once again, this time as an internment camp for local German residents who were suspected (almost always falsely) to be conspiring with the enemy. It hasn’t been used as an active gaol since, and is now an historic ruin.
