Táin Bó Cúailnge
In Irish mythology Cooley (Old Irish "Cúalnge") was the home of the bull Donn Cuailnge, and the site of the "Táin Bó Cúailnge" "Cattle Raid of Cooley". Ancient monuments in Cooley include the Proleek Dolmen, whose capstone weighs an estimated 35 tons (31.75 tonnes), and a Bronze Age gallery grave, both near Ballymascanlan.
