"Visually distinct from the densely-built urban blocks" and open, city park landscape around it, this district's structures were designed between 1849 and 1922 in Gothic Revival, Italian Villa, Queen Anne, Tudor Revival, Shingle, and Colonial Revival styles of architecture. The grounds of the Awbury Arboretum were designed by William Saunders, the prominent landscape architect who designed the Gettysburg National Cemetery and helped to design Fairmount Park. A Victorian-style garden was also created near the Francis Cope House through the joint efforts of the Philadelphia Garden Club and the Weeders Garden Club. Placement of this district on the National Register of Historic Places In August 2000, Philadelphia area newspapers reported that representatives of the Awbury Arboretum had submitted the necessary paperwork to initiate the creation of the Awbury Historic District and secure its placement on the National Register of Historic Places. That paperwork was then reviewed for its suitability for the NRHP by Pennsylvania's Historic Preservation Board at its March 13, 2001 meeting at 9:45 a.m. at the State Museum in Harrisburg. Also considered for NRHP status at this time were the: Protection of the Flag Monument in Athens, Pennsylvania; Normandy Farm, George K. Heller School, and Upper Roxborough Historic District in Montgomery County; Harris/Laird, Schober & Company Building in Philadelphia; Michael Derstine Farmstead in Bucks County; Chester Heights Camp Meeting Historic District in Delaware County; John Nicholas and Elizabeth Moyer House in Berks County; William Shelly School and Annex in York County; and the Zeta Psi Fraternity House in Northampton County. This district was then officially added to the National Register in May 2001, an achievement that was recognized on September 23 of that year with a day of free educational activities for the public, including tours of several of the district's most prominent homes.
