Albert Square was part of mid-C19th development in the area that was previously market gardens and agricultural land. Built by Islington builder John Glenn, the square was laid out on as grand a scale as in Kensington.
The 4-storey houses enclosed a private communal garden provided for the use of residents. Now open to the public, the square is largely grassed and has slightly undulating ground with perimeter trees and modern railings. Mature trees include London plane and holly.
