The Washington Monument is an obelisk on the National Mall in Washington, D.C., built to commemorate George Washington, a Founding Father of the United States, victorious commander-in-chief of the Continental Army from 1775 to 1783 in the American Revolutionary War, and the first President of the United States from 1789 to 1797. Standing east of the Reflecting Pool and the Lincoln Memorial, the monument is made of bluestone gneiss for the foundation and of granite for the construction. The outside facing consists, due to the interrupted building process, of three different kinds of white marble: in the lower third, marble from Baltimore County, Maryland, followed by a narrow zone of marble from Sheffield, Berkshire County, Massachusetts, and, in the upper part, the so-called Cockeysville Marble. Both "Maryland Marbles" came from the "lost” Irish Quarry Town of "New Texas". It is both the world's tallest predominantly stone structure and the world's tallest obelisk, standing 554 feet 7+11⁄32 inches (169.046 m) tall, according to U.S. National Geodetic Survey measurements in 2013–2014. It is the tallest monumental column in the world if all are measured above their pedestrian entrances. It was the world's tallest structure between 1884 and 1889, after which it was overtaken by the Eiffel Tower, in Paris. Previously, the tallest structures were Lincoln Cathedral and Cologne Cathedral.

Back Creek originates along Frederick County's border with Hampshire County, West Virginia, at Farmer's Gap in the Great North Mountain. Its name reflects its location to the west of North Mountain. The perspective of colonists from the east in the 18th century led them to call it "Back Creek", because it lay to the back of North Mountain.

Designed by Jacob Linville, the bridge has 46 spans: 25 deck plate girder, 14 deck truss, 6 through truss, and 1 through plate girder. 50,000 cubic yards (38,000 m3) of stone were used for the 53 piers.

A spring house, or springhouse, is a small building, usually of a single room, constructed over a spring. While the original purpose of a springhouse was to keep the spring water clean by excluding fallen leaves, animals, etc., the enclosing structure was also used for refrigeration before the advent of ice delivery and, later, electric refrigeration. The water of the spring maintains a constant cool temperature inside the spring house throughout the year. Food that would otherwise spoil, such as meat, fruit, or dairy products, could be kept there, safe from animal depredations as well. Springhouses thus often also served as pumphouses, milkhouses and root cellars.
The boundary markers of the original District of Columbia are the 40 milestones that marked the four lines forming the boundaries between the states of Maryland and Virginia and the square of 100 square miles (259 km2) of federal territory that became the District of Columbia in 1801. Working under the supervision of three commissioners that President George Washington had appointed in 1790 in accordance with the federal Residence Act, a surveying team led by Major Andrew Ellicott placed these markers in 1791 and 1792. Among Ellicott's assistants were his brothers Joseph and Benjamin Ellicott, Isaac Roberdeau, George Fenwick, Isaac Briggs and an African American astronomer, Benjamin Banneker.

George Washington's Gristmill was part of the original Mount Vernon plantation, constructed during the lifetime of the United States' first president. The original structure was destroyed about 1850. The Commonwealth of Virginia and the Mount Vernon Ladies’ Association have reconstructed the gristmill and the adjacent distillery. The reconstructed buildings are located at their original site three miles (4.8 km) west of the Mount Vernon mansion near Woodlawn Plantation in the Mont Vernon area of Fairfax County. Because the reconstructed buildings embody the distinctive characteristics of late eighteenth century methods of production and are of importance to the history of Virginia, the site is listed on the National Register of Historic Places despite the fact that the buildings are not original.
