Check out this beautiful drone video of Derry in Northern Ireland, compliments of contributor imaginelight. Also known as Londonderry, it's the second largest city in British Ulster after Belfast. It's one of the oldest continuously inhabited settlements on the island. Its old walled city is situated on the west bank of the River Foyle, in the northwestern corner of the province. It is geographically and to some extent culturally close to County Donegal, the northernmost county of Republican Ireland.
