Nightingale Square offers sloping gardens on three levels, surrounded by hedging, shrubs and a diverse collection of 85 trees. Some 22 of these are more than 50 years old and some have reached their centenary and beyond. The trees are predominantly broad-leaved and deciduous and offer shade, colour, flowers, fruit and seeds spanning the four seasons. The railings were replaced in 1999 to their pre-war condition. The surrounding houses date from the late 19th century and the church of the Holy Ghost (1897) is by Leonard Stokes.
