Brooks Mansion is composed of the original Greek Revival mansion house, Bellair, built by Ann and Jehiel Brooks circa 1840, and a large eastern addition to this house built by the Marist Society which altering Bellair for use as Marist College in 1894.
There was lawn to the north and east and a pear orchard to the west of the drive. A long walled garden containing a greenhouse, well, flower and vegetable garden and grapery with a variety of plum, cherry, apricot, nectarine and fig-bearing trees extended from the west side of the house. A peach orchard was to the east, and an open field and apple orchard were to the south.
The grounds of Brooks Mansion uniquely reflects the history of the development of Brookland, from Colonial days to the present. Brooks Mansion is a fine example of Greek Revival architecture, built in the late 1830s, when the enthusiasm for Greek Revival was at its height. The purity of its Greek Revival design is unusual in Washington. Here, despite the presence of such extraordinarily fine Greek Revival monumental public buildings as the U.S. Treasury and the U.S. Patent Office, residential architecture remained strongly under the influence of the federal tradition.
