Past features of Round Hill include a windmill, which took advantage of the windy conditions on the 223 feet hilltop until 1913; 19th-century laundries, which sought the same advantage; early 19th-century pleasure gardens, now occupied by the houses of Park Crescent; the landmark Cox's Pill Factory, demolished in the 1980s; glasshouses and smallholdings, some of which survived until after the Second World War despite being surrounded by houses; and the Kemp Town branch line, a passenger and freight railway which cut through the area and had a short-lived station serving Round Hill.
