Port Arthur is now a World Heritage Site, however, 1830, it was the new site of a prison for convicts. Only reoffenders and people whose behaviour in other prisons was considered difficult were housed here. Prisoners worked hard in the shipyard, construction, gardening, and leatherwork which provided for the local community of officials. The work was hard and punishments harsh for prisoners, while officials enjoyed many luxuries. Prisoners were kept separate from officials. In fact, while officials and their families took part at Mass, prisoners could only listen from behind curtains. The young offenders, as young as nine years of age, were housed on an island not far from the colony. Next to that island was the Isle of the Dead, a cemetery where the officials and their families were buried in marked graves on high ground and prisoners in unmarked graves else where. Today, a rainbow marked this island, a sign of hope for all.
