Idlewild is a historic building near Media, Pennsylvania, designed by the Victorian-era Philadelphia architect Frank Furness as a summer cottage for himself and his family. He spent summers there until his death in 1912. The house was built about 1890 on the grounds of the Idlewild Hotel, which Furness had designed in 1886. This was a mile west of "Lindenshade," the Wallingford summer house of his brother, Shakespearean scholar Horace Howard Furness. It was also a short walk to the Moylan-Rose Valley train station, which enabled him to commute to his architectural office in Philadelphia. * * *
