Montagu Square is Westminster's only remaining purely residential square and it has a beautiful, tranquil, shady garden. The square was laid out by the estate's architect, James Thompson Parkinson, around 1800 and named after Elizabeth Montagu of nearby (now demolished) Montagu House. She is remembered for her literary Blue Stocking Society and the annual May Day party for chimney-climbing boys attended by, among others, a young David Porter. He started life as a chimney sweep but grew up to be the builder of Montagu Square. More recently, the residents restored the railings, which had been removed during WWII.
