Geneva Barracks

Geneva Barracks in County Waterford, Ireland, was a barracks created in 1783 by converting a settlement which had been created for an 18th-century colony of disaffected citizens of Geneva following the Geneva Revolution of 1782. Built near Passage East, the colony was commissioned by the Irish Parliament and approved by the Crown. After the Genevans abandoned their plans to settle in Waterford, the colony became a military barracks instead. During the Irish Rebellion of 1798, the barracks was transformed into a holding centre for captured United Irishmen rebels, many of whom were executed, transported or conscripted. Today, the only remains of New Geneva are its ruined walls in a grassy field.
