A later colonial convict settlement began in 1825, when it was decided that a final place of punishment was needed for recidivists and other antisocial British subjects, such as Irish political prisoners.

These were the dark days of the Island, both in terms of human crutlty and degradation.

This period also marked the beginning of the decimation of the island's natural biota, as clearing for large-scale agriculture and ambitious building works began.

This cruel erra ended in 1855 with the removal of the last of the convicts, as deportation become less popular and other programs for the utilisation of convict labour became favoured.
