This is the Convict Brick Trail in Campbell Town, Tasmania. The bricks are dedicated to some of the convicts who were transported to Australia from 1788, for almost one hundred years.
The trail was a privately organised project, with bricks purchased and details provided by individuals or descendants of the convicts identified on the brick.
Each brick states the name and age of the person, the ship they arrived on, their crime and sentence. Also, some other piece of information, perhaps where they were from, who they married, where they died, their achievements (or otherwise) in their new land.
Even James Bond gets a mention!?!
