Holly Hill (Friendship, Maryland)

Holly Hill, also known as Holland's Hills or Rose Valley, is a historic house at Friendship, Anne Arundel County, Maryland, United States. It was originally a primitive, two-room,  1 ¹⁄₂-story frame dwelling constructed in the fall or winter of 1698. An addition was made in 1713, and about 1730 the entire structure was encased in brick and another addition was constructed. The house is an example of the Medieval Transitional style of architecture. It was a quarter plantation of Richard Harrison, who likely built the original structure for his son, Samuel Harrison (1679–1733).

Ownership of Holly Hill continued in the Harrison family until 1850; then, after a brief interregnum, it was the home of a branch of the Scrivener family until its purchase in the late 1930s by Captain and Mrs. Hugh P. LeClair. The LeClair family performed an extensive restoration of the house and added a kitchen wing and a detached garage in faithful Tidewater style. In 1968 Holly Hill was purchased by Brice McAdoo Clagett (1933–2008), a descendant of Richard Harrison. Mr. Clagett and his first wife, Virginia P. Clagett, added extensive ornamental plantings and gardens to the grounds near the house.

Holly Hill was listed on the National Register of Historic Places in 1971. Holly Hill is protected by conservation easements that are held by Maryland Environmental Trust and Maryland Historical Trust.
