The Searles Castle is located in Windham, New Hampshire, in the United States. It was ordered to be built by Edward Francis Searles. Construction began in 1905 and was completed in 1915. It was intended to be a 1/4-scale replica of the medieval Tudor manor of Stanton Harcourt in Oxfordshire, England, but since most of the manor had been torn down in the 18th century, the castle bears little resemblance to the historical structure.
