Compton and Bloomfield
Also known as: Morris Arboretum
Why it's listed
Set on the hills of Chestnut Hill at the northwestern edge of Philadelphia, this former estate was begun in 1887 when John T. Morris and his sister Lydia T. Morris acquired land and commissioned Theophilus Parsons Chandler to design the greystone mansion Compton. Morris, who retired from the family iron works in 1891, turned his attention to an arboretum that grew into a landscape of specimen trees, theme gardens, pools and garden architecture. The Morrises willed the property to the University of Pennsylvania, which has administered its 180 acres since. The grounds include a carriage house-stable by Chandler from 1906, a gardener's cottage by Cope and Stewardson from 1904, and the David W. Pepper house, now Gates Hall, by Wilson Eyre, Jr. Its garden structures, among them a tholos by the Swan Pond and a Mercury Temple of 1913, draw on English models. The property is regarded as an important example of an old Philadelphia family's estate, with buildings that span the 18th to 20th centuries.
Significance in brief: The nomination argues the arboretum reflects the life style of an established Philadelphia family, John T. and Lydia T. Morris, and an 18th and 19th century romantic tradition joining aesthetic perception to scientific study. It also points to a group of architecturally significant buildings by noted Philadelphia architects, including the Pepper house, described as a major transitional work in Eyre's oeuvre, and to garden features modeled on English precedents.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
