Winged Angel and War Memorial. It is in a small park named Spa Green on Rosebery Avenue.

Spa Fields (which is now memorialized as the name of the housing estate next to the park), for which the park is named, was a slum in Dicken’s time. He mentions it in “The Old Curiousity Shop” as the winter home of carnival folk:

“Why, I remember the time when old Maunders as had three-and-twenty wans—I remember the time when old Maunders had in his cottage in Spa Fields in the winter time, when the season was over, eight male and female dwarfs setting down to dinner every day, who was waited on by eight old giants in green coats, red smalls, blue cotton stockings, and high-lows: and there was one dwarf as had grown elderly and wicious who whenever his giant wasn’t quick enough to please him, used to stick pins in his legs, not being able to reach up any higher. I know that’s a fact, for Maunders told it me himself.’ “
