Culmore (from Irish Cúil Mór, meaning 'the great corner')[1] is a village and townland in Derry, County Londonderry, Northern Ireland.

Sir Henry Docwra, 1st Baron Docwra of Culmore, was an English soldier who landed with a force of 4000 foot and 200 horse troops at Culmore on 16 May 1600, as part of an attempt to quell a war against the crown in Ulster.

He served as Governor of Loughfoyle, and on 15 May 1621, by a patent dated at Westminster, was created Baron Docwra of Culmore.

Culmore Fort was an important strategic position linked to the garrison town of Derry.

In 1608 when Sir Cahir O'Doherty, a formerly loyal Gaelic leader, launched O'Doherty's Rebellion by seizing and burning Derry he began by first capturing a supply of arms from the arsenal at Culmore after capturing its commander Captain Henry Hart.
