The house is a large three-story wood frame structure, set on a lot roughly in size, built in 1791 for Colonel Joseph Nightingale. Its main facade is five bays wide, with a central projecting section. The center entrance is framed by sidelight windows and topped by an elliptical fanlight window. This framing is one of the earliest known uses of such windows in the United States. The entrance is sheltered by a square porch supported by columns, with a low railing above. Atop the doorway is a Palladian window, whose side windows are topped by dentillated cornices. The projecting section is topped by a triangular pediment, whose deeply recessed tympanum is modillioned and filled with a window. The corners of the projecting section, and of the main and side blocks, are all quoined, and the window surrounds on the first two floors also feature quoined and voussoired surrounds. The main block is covered by a hip roof, with a low balustrade surrounding it. This appearance largely matches the first known image of the house, a drawing made in 1802. In 1814, Nicholas Brown, Jr. purchased the home. His descendants owned the house until the death of Anne S.K. Brown in 1985, at which point it was donated to Brown University. In 1853 John Carter Brown hired Thomas Tefft to design a carriage house for the property, and in 1858 a two-story addition was added to the south side. It is unknown if Tefft was involved in the design of the addition, but it has stylistic similarities to the carriage house. In 1862 Brown hired Richard Upjohn to design a library wing, which was built in 1862–1864 and is northeast of the main block and forms a courtyard with the carriage house. This addition, like the earlier one, repeats stylistic elements of the original 1791 structure. Frederick Law Olmsted was hired to design the landscaping for the grounds in 1890; this work is still evident despite modest alterations.
Occupants
Nicholas Brown, Jr. was the son of Nicholas Brown, Sr., a leading Providence merchant. He was a leading industrial developer of the early 19th century, and was such a benefactor of the local college that it was renamed Brown University in his honor. He also served in the state legislature, and cofounded the Providence Athenaeum. John Carter Brown is best known for amassing a large library, now owned by the university and operated as the John Carter Brown Library. Anne S. K. Brown, the last Brown descendant to live in this house, amassed a large collection of military documents and artifacts, which are also now owned by the university. Her son, J. Carter Brown, who directed the National Gallery of Art, was raised in the house.
John Nicholas Brown Center for Public Humanities and Cultural Heritage
The is currently housed in the building. The Center, founded as the John Nicholas Brown Center for the Study of American Civilization in 1979 and part of Brown University since 1995, collaborates on public and scholarly humanities projects with local, national, and international partners working in the arts, history, education and community engagement. The Center also offers a master's degree in Public Humanities through Brown.
