The Freedom of Dublin city remains largely ceremonial in contemporary Ireland, though historically it carried specific rights and responsibilities that holders were required to maintain. Whilst freemen and women enjoyed the privilege of grazing sheep on College Green or St Stephen's Green, they were also obligated to stand ready to protect Dublin city from invasion. Ancient Privileges include:The right to bring goods into Dublin through the city gates, without paying customs duties. Ancient Duties include:Each Freeman or Freewoman must be ready to defend the city from attack. In a letter to the Obamas, Lord Mayor Ray McAdam said he would be happy to host a full meeting of Dublin City Council to formally award the honour to them.
