List of houses in Fairmount Park

Most of the houses are referred to as mansions due to their size and use as the summer country estates of Philadelphia's affluent citizens in the 18th and 19th centuries.

Other historic houses were demolished due to extensive deterioration, vandalism, fire damage or insufficient funds for restoration.

Three additional historic park buildings were designed like residential houses though they were never intended to be used as private residences: the Ohio House—built by the Ohio delegation for the Centennial Exposition; the Shofuso Japanese House—built in Japan as a museum exhibit for display at MoMA, then relocated to Fairmount Park; and the Smith Memorial Playhouse—designed, and still used, as an indoor play area for children.

[4] The lessees must commit to rehabilitate and maintain the buildings, without altering their historic architectural features, while allowing public access.

The trust offers assistance to prospective lessees in assessing feasibility, identifying financial incentives, and managing rehabilitation and maintenance work.
