The Rock of Cashel or Síd Druim

This is one of Tipperary's most iconic sites but not many probably know about its faery side. Professor Ronald Hicks has this to say "Síd Druim – "Síd ridge," more commonly known as the Rock of Cashel or St. Patrick's Rock, in County Tipperary. It became the royal seat of Munster, perhaps as early as the fifth century. The name is actually shared with a variety of other sites that we will visit later. There seems to be a dialect difference further north, where the name appears as Síd Truim in County Meath and as a whole cluster of Sheetrim townlands in counties Armagh (2), Fermanagh (1), and Monaghan (3)."
