The Philadelphia Society for the Preservation of Landmarks (PSPL) is dedicated towards preserving items of architectural significance in Philadelphia. For over 70 years, PSPL has played a significant role in preservation in Philadelphia by restoring and presenting to the public its historic house museums. PSPL was founded in 1931 by Frances Anne Wister, and today administers three historic houses and historic Waynesborough. In addition, PSPL offers Landmarks Exhibitions, a new initiative that "includes both special historically-based exhibitions by guest scholars, and an ongoing series of site-specific installations and experiemental performers by the innovative artists of today." PSPL is also a major supporter of the Philadelphia Orchestra, Philadelphia Museum of Art, the Philadelphia Flower Show, and the Barnes Foundation.

Ardenwood Historic Farm is the historic home of George Washington Patterson. Patterson came west in 1849 during the gold rush to seek his fortune; instead he settled at Ardenwood Farm in southern Alameda County. The Historic Farm is faithfully restored and features agricultural practices from the 1870s to the present, demonstrating the transition from horse-powered equipment to modern farming equipment. There are more attractions than just the house, however. The park also features a horse-drawn train, victorian garden, animal farms, and a restored blacksmith shop.

The site offers general information about the park for visitors, a calendar of events, a trail map, and information regarding field trips for educators.

The Joseph Manigault House sits in downtown Charleston near the City Visitor Center. The house was designed by gentlemen architect Gabriel Manigault for his brother, Joseph. Joseph owned plantations, sat in the state legislature, and was a trustee of the College of Charleston. Gabriel, who owned plantations and commercial investments, is credited with designing Charleston’s City Hall and the South Carolina Society Hall. The house is an exceptional example of Adam-style, or Federal, architecture. The house has been restored and is furnished with American, English, and French pieces of furniture from the early 19th century. In addition, outside the house is a beautiful period garden.

The site offers general information about the Joseph Manigault House, but is part of the Museum of Charleston web site, which features an event calendar, general visitor information, general information on all current and past exhibits, a museum store, and resources for educators including programs for elementary, middle, and high school students.
