Fly/ St. Inigoes Manor House
c. 1680 - 1750
Sites 18ST329 (Fly) and 18ST330 (St. Inigoes
Manor House) are located aboard the Naval Air Station Patuxent
River’s Webster Field Annex in St. Inigoes, Maryland.
In 1637, Jesuit missionaries purchased the land where the sites
are located and established a settlement there. These Jesuits
were among the original investors in the Maryland colonial enterprise.
The settlement at St. Inigoes was a working farm where inhabitants
raised tobacco and other crops to support the Jesuit mission.
The earliest center of activity for the Jesuit
plantation is most likely represented by a site that neighbors
18ST329 and 18ST330, Old Chapel Field (18ST233). The Fly/St.
Inigoes Manor House site seems to have been the center of domestic
activity on the settlement from c. 1680-1750, but a few early
artifacts indicate that it also may have served a non-domestic
function associated with the nearby mid-17th century occupation.
A series of studies of Webster Field have been conducted by
the Southern Maryland Regional Center. The sites were identified
by a 1981 field school, and further phase I testing took place
in 1984 and 1996. When identified, 18ST329 and 18ST330 were
designated separately based upon their location on either side
of a modern road. Later projects proved that both sites had
a historic component relating to the early 18th-century St.
Inigoes Manor House, so the division was unnecessary.
Phase II testing of 18ST329/18ST330 and 18ST233
was undertaken in 2000. This project concentrated on features
found during the 1984 survey. One of the features was a brick
floor that, when exposed, proved to cover a 10 x 10 ft. area.
The bricks appeared to have been lain inside an existing timber
framed structure because at the corners they were placed to
The excavation of the brick floor exposed an
older cellar beneath it which had several intact architectural
elements such as a wooden sleeper for floor joists, intact studs,
and large limestone pavers that ran parallel to the sleeper.
The cellar was presumably dug in the late 17th or very early
18th century. The cellar fill included soils that had apparently
eroded into the area, covering the limestone pavers. Later rubble
from the collapse of a wall and a fireplace added to the fill.
The brick floor was then placed atop the old cellar. The function
of this structure is unknown, but it is clear that it was adapted
and reused over time.
