Mornington Crescent is a street in Camden, London, England. It was built in the 1820s, on a greenfield site just to the north of central London. The crescent was named after the Earl of Mornington, brother of the Duke of Wellington. Comprising three curved terraces grouped in a crescent form around communal gardens, the north side of the crescent (numbers 37-46) was constructed first, dating from the 1820s or earlier. With 36 spacious houses suitable for professional people, the crescent was originally surrounded by green fields, enjoying views across open country to the front and rear, yet was conveniently close to town.
