Inscription.

Dunseverick Castle and its rocky peninsula were given to the National Trust in 1962 by farmer Jack McCurdy.

The term Dun (fort) indicates a royal site. This was the fort of Sobhairce. It may have been a royal stronghold in the Iron Age (around 500 B.C.) and traditionally was one of the great duns of Ireland.

St. Patrick reputedly visited Dunseverick in the 5th Century. The extensive earthworks on the headland may be the remains of the royal fort from which the Antrim kingdom of Dalriada was ruled in the Early Christian period. It was attacked and captured by Vikings in 871 and later destroyed by them in 926.

The ruined 16th century stone tower remains from the period of struggles for supremacy between the main families - the MacDonnells, O'Neills, O'Cahans and MacQuillans.

The Eider, a large sea duck, inhabits the bays along this coast all the year round. The male is black and white, the female brown. In summer, the male moults to a similar colour to the female. The female rears her young alone on nearby islands and below isolated headlands. She lines her nest warmly with feathers plucked from her own breast.

This is the well known Eider-down.

From spring through to autumn, the coarse grasslands of the cliff tops and slopes may be sprinkled with mainly cream canopies of a range of flower species belonging to the family Umbelliferae. The umbel is the name for the clustered arrangement of the flowers Alexanders in April (favouring road verges), Pignut in May, Hogweed in June, Wild Carrot in July, Angelica in August and Yarrow throughout summer to autumn, some remaining in bloom into winter. These flowers are popular with insects, from small flies to orange soldier beetles.
