Place & story

Between Foyle and Bann

Lewis's 1837 county account places the territory between Lough Foyle, the Atlantic and County Antrim, with Tyrone to the south. He recalls the earlier name County Coleraine and the O'Cahan or O'Kane lordship in the Roe Valley. The historical county is larger than Derry city. Its coast, inland valleys and southern lough-side country supplied varied settings for settlement, farming and trade. [2]

People & connections

Seamus Heaney at Mossbawn

Seamus Heaney was born in 1939 at Mossbawn, a family farm near Castledawson. HomePlace's biographical account follows his childhood there and at The Wood outside Bellaghy, and his schooling at Anahorish and St Columb's College in Derry. His connection with the county is both rural and urban. Later international recognition did not erase those beginnings: the landscapes and work he knew as a child remained important to his writing. [3]

Places behind the poems

HomePlace's Open Ground project identifies particular locations associated with Heaney's work, including the Moyola River, the Strand at Lough Beg, Magherafelt and Bellaghy Bawn. They also show how ordinary places—a riverbank, a bus station or ground used for grazing—can acquire significance through a writer's remembered experience. [4]

Folklore & tradition

Protection on Hallow Eve

Elizabeth Andrews's Ulster Folklore, published in 1913, records a belief she first encountered in the Roe Valley: oatmeal and salt were placed on children's heads on Hallow Eve to protect them from fairies. She also describes warnings near Dungiven against disturbing stones at an ancient site. [5]
