County Londonderry, Historic county in Northern Ireland
County Londonderry extends over 2,074 square kilometers of varied terrain, including mountains, valleys, and rivers along the northwestern coast of Northern Ireland.
The county formation occurred in 1613 when King James I merged the existing County Coleraine with additional territories to establish administrative control.
The region maintains two parallel naming traditions, with Derry and Londonderry both used according to different community preferences and historical contexts.
Three district councils manage the administrative functions across the county: Derry and Strabane, Causeway Coast and Glens, and Mid-Ulster District.
Sawel Mountain marks the highest elevation at 678 meters, standing on the border with County Tyrone and offering views across multiple counties.
