Roundwood Park is a public park in Willesden, London, measuring a total of 26.5 acres, or approximately 10.27 hectares. It was originally known in the 19th century as Knowles Hill (its name coming from the Knowles Tower nearby), or Hunger Hill Common Field, and after much work by Oliver Claude Robson, became the Roundwood Park known to the public today (its name coming from the Roundwood House originally beside it).
