Dulwich Park is a 30.85-hectare (76.2-acre) park in Dulwich in the London Borough of Southwark, south London, England. The park was created by the Metropolitan Board of Works from former farmland and meadows. While the initial design was by Charles Barry (junior), it was later refined by Lt Col J. J. Sexby (who also designed Battersea and parts of Southwark Parks). It was opened in 1890 by Lord Rosebery. In 2004–6, the park was restored to its original Victorian layout, following a grant from the Heritage Lottery Fund. It is home of Dulwich Park Runners, a minor running club.
