Louisburgh preserves local memories of the famine, examines national and local media coverage of it, traces links established between Louisburgh and other parts of the world, and culminates in the local famine walk along Doo Lough Valley. It also presents the life and times of the 16th century O'Malley chief and sea captain Granuail, also known as Grace O'Malley or Gráinne Uaile, who led the shipping fleet that reigned supreme in Clew Bay at that time.
