Chamounix is a historic home located in Fairmount Park, Philadelphia, Pennsylvania. The Federal-style house was built in 1802 by George Plumsted who was a wealthy Philadelphia merchant, then enlarged to nearly double its original size by subsequent owners after 1853. Chamounix is a 2½-story stuccoed stone dwelling measuring 45 feet (14 m) long and 47 feet (14 m) deep, featuring a hipped roof with dormers and a porch on three sides with decorative iron supports. The house served as a country retreat until it was appropriated by the state via eminent domain in 1869 to become a part of Fairmount Park, from which time it was used in various ways including as a boarding house, a restaurant, and a refreshment stand. After years of neglect and then fire damage, the Fairmount Park Commission decided to demolish Chamounix; however, a committee of the former American Youth Hostels (AYH, now HI USA) successfully petitioned to save it and, since 1964, it has served as an international youth hostel.
