Sydenham is split into "upper" and "lower" areas along a gradual incline towards Crystal Palace, considered the fourth highest point in central London. Upper Sydenham still bears the characteristics of the affluent Victorian suburb it once was, whilst Lower Sydenham and the areas overlapping into Perry Vale feature significant social housing and a large retail park.
