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 is a 1/4-scale replica of the medieval Tudor manor of Stanton Harcourt in Oxfordshire, England.
In 1991, in an effort to restore the interior of the castle, a "Decorators' Showcase" was held. Through the generosity of those interior designers and contributions received over the years from many benefactors, the interior of the building has been refurbished. Since that time, the castle has been available to the public for social, cultural, religious, and business events.
