New Castle or Greencastle

History of New Castle

New Castle (also known as Greencastle or Northburgh Castle) was a Norman castle built in 1305 by the de Burgh family, the Earls of Ulster. Around 1333 the de Burgh family lost power and New Castle became an Ó Dochartaigh stronghold for over three centuries following. O'Clery mentions a group of Ó Dochartaighs living at New Castle in the mid-1600s.
