History & Heritage

Derry city — called Londonderry by the British government and much of the Protestant community — is one of the last completely walled cities in Europe. The walls, built between 1613 and 1619 by the London guilds who funded the Plantation, are 1.5 kilometres in circumference and largely intact. The Siege of Derry in 1689 — a 105-day Jacobite siege that failed — is one of the foundational events of Ulster Protestant identity.

The county is the homeland of Seamus Heaney — Nobel laureate, Ireland's greatest modern poet. Heaney grew up in Bellaghy, County Derry, and the landscape of the county — its bogs, farms, and mythological associations — runs through almost everything he wrote. The Seamus Heaney HomePlace in Bellaghy is now a major cultural centre.

Doherty — from Ó Dochartaigh ('descendant of the obstructor') — is the most characteristic surname of County Derry and the wider Inishowen peninsula. It is among the most common surnames in both Donegal and Derry.

The County Derry Diaspora in America

Derry city was one of the great emigration ports of the nineteenth century. Thousands of emigrants departed from Derry Quay for North America — particularly for Canada's eastern provinces (New Brunswick, Nova Scotia, Prince Edward Island). The 'Derry port emigrants' have a distinct genealogical identity.
