The Royal County of Berkshire Real Tennis Club operates the real tennis court at Holyport, Berkshire, England. The court was built in 1889 by Sam Heilbut as part of his Holyport estate. For years Holyport was owned by the Martineau family, and a real tennis club was formed in 1953. When the last Martineau, Mrs. Janne Cahill, died in the 1980s, a small group led by Chris Ronaldson, Colin Lumley, and other tennis enthusiasts bought the court and an area of surrounding land. The court is tucked behind a row of picturesque cottages on Holyport Street. The main house of the estate is now a nursing home.
