. Not far from Peter's property, John Garrett laid out a community in 1787. He called it Newport, and it was located on the west side of the mouth of Great Seneca Creek, on the Potomac River and about upriver from
Georgetown. The Newport name did not last long—the locals called the community Seneca.
Robert Peter died in 1806, and his eldest son Thomas inherited land near Seneca including the quarry.
Construction of the
Chesapeake and Ohio Canal
The Chesapeake and Ohio Canal, abbreviated as the C&O Canal and occasionally called the "Grand Old Ditch," operated from 1831 until 1924 along the Potomac River between Washington, D.C. and Cumberland, Maryland. It replaced the Potomac Canal, wh ...
(a.k.a. C&O Canal) along the Potomac River began on July 4, 1828.
The canal was necessary because portions of the river were too shallow and rocky for freight boat traffic. By that time, the Seneca Quarry and some nearby land on the Potomac River were owned by John Parke Custis Peter, the eldest son of Thomas and Martha Peter.
The canal increased the importance of Seneca, and C&O Canal Lock 24, now known as
Riley's Lock

carries the canal over Seneca Creek near the community. By 1833, enough of the canal was completed to enable canal service between Georgetown and Lock 24, and further upriver—providing access to new markets for Peter's sandstone quarry. Portions of the canal locks and lock houses were constructed using the quarry's distinctive red sandstone. The same quarry, with its own
stone-cutting mill, was used to produce material for buildings in Washington such as the
Smithsonian Institution Building

The canal also opened markets for area farmers. John Darby, and his son Upton, purchased the Seneca grist mill in 1855.
In addition to milling operations, Darby's company shipped products on the C&O Canal. They had a warehouse on the creek (near Lock 24) and their own canal boats.

troops occurred nearby, including an attack in 1863 that damaged nearby canal infrastructure. After the war in 1866, the Peter family sold the quarry and nearby property to the newly created Seneca Sandstone Company. Upton Darby donated land for a one-room schoolhouse that was built using red sandstone from the local quarry.
An 1879 Montgomery County directory lists Seneca as having "public schools and churches in the vicinity". The community also had a store and post office.
However, freight traffic on the C&O Canal had already peaked in 1871, starting a downward trend that would end with the canal closing permanently in 1924.
As the canal declined, Seneca declined, and the permanent closure of the canal caused Seneca to lose its relevance.
The school closed in 1910.

. The Seneca Mill, a gristmill also known as the Darby Mill and later the Tchiffely Mill, was located on the west side of Seneca Creek about 0.5 miles north of River Road. The mill burned around 1956 and the ruins were destroyed when
River Road was widened in the 1960s.
In 2021, the radio telescope is gone and the site is now part of the
McKee-Beshers Wildlife Management Area. A historical marker commemorating the discovery is located on River Road at the management area's parking lot.
All that remains of Seneca are a few homes, the schoolhouse as a museum, the store, and ruins of the stone-cutting mill and quarry. The community is still listed by the United States Geological Survey as a populated place.
Geography
Seneca is a populated place that is not a census-designated or incorporated place having an official federally recognized name. Previous names for the community are Newport and possibly Middlebrook Mills. Seneca is located in Montgomery County, Maryland.
The USGS defines a populated place as a place or area with clustered or scattered buildings and a permanent human population (city, settlement, town, village). A populated place is usually not incorporated and by definition has no legal boundaries. However, a populated place may have a corresponding "civil" record, the legal boundaries of which may or may not coincide with the perceived populated place.
Seneca is located close to the intersection of River Road (Maryland Route 190),
Seneca Road (Maryland route 112), and Rileys Lock Road, east of Great Seneca Creek and north of the Potomac River. The C&O Canal runs along the river, and Riley's Lock is the closest canal lock. The southern portion of
