[3] St. Ignatius Roman Catholic Church, which is located in St. Inigoes, was listed on the National Register of Historic Places in 1975.

It also hosts a small naval air facility called Webster Field, as well as Coast Guard Station St. Inigoes, and is the site of the USS Tulip Civil War monument.

[10][13][14] In December 1784, Father James Walton ordered the enslaved people residing at the St. Inigoes Jesuit-owned plantation to begin building a new church after the destruction and chaos caused from the American Revolutionary War.

[15] The parish also includes part of one of the nation's oldest known African American Catholic communities, which has an even larger presence in neighboring Ridge.

The erosion-prone quality of the shoreline caused the fort to be undermined by waves and the area collapsed into the St. Marys River before the 1800s.

During 1813, a secret pony express was run through St. Inigoes from a clandestine American intelligence force in Point Lookout.

[12] For example, Granny Sucky was a ninety-six-year-old enslaved woman at the time of her interview, who shared that Father John Bolton of St. Inigoes beat her when she was a child (in the mid-18th century) for interrupting his self-flagellation.

[18] Coast Guard Station St. Inigoes is located near the naval facility and is charged with rescue, law enforcement, safety education and protecting citizens in area waters.

[19] St. Inigoes is also home to the USS Tulip monument, located a short walk from near the end of Cross Manor Road.

The Tulip was originally commissioned as a Chinese naval vessel but was acquired by the U.S. Navy in 1863 for use in the Potomac flotilla during the Civil War.

[5][6] There is a small public park and recreational-boat landing managed by the St. Mary's County Recreation Division on Beachville Road.

[8] There are some boat landings and docks on various coves and creeks in St. Inigoes, which support a now-dwindling population of traditional St. Mary's County "watermen" (oyster and crab fisherman).

Some tracts of farmland are on parcels of larger, former slave plantations and still produce tobacco, corn and soy crops yearly.

[21] St. Inigoes is one of the few remaining places in St. Mary's County where older families retain hints of the speech of the area's original English and Irish colonial settlers.

These accents are in the process of dying out with the decline of the fishing community, the conversion of farmland to residential development and the influx of new residents.

[22] The growth of the St. Mary's County population has brought change to St. Inigoes, and the number of tiny residential developments have grown since the late 1980s, especially along waterfront and cove areas.

There is also a small community of traditional St. Mary's County watermen (fishermen and crabbers) and their families that remains interspersed throughout parts of the newer development.
