Contributing property in the context of "Marine Barracks, Washington, D.C."

The National Register of Historic Places (NRHP) is the United States federal government's official list of sites, buildings, structures, districts, and objects deemed worthy of preservation for their historical significance or "great artistic value."

The enactment of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts.

Fort de Chartres was a French fortification first built in 1720 on the east bank of the Mississippi River in present-day Illinois. It was used as the administrative center for the province, which was part of New France. Due generally to river flooding, the fort was rebuilt twice, the last time in limestone in the 1750s in the era of French colonial control over Louisiana and the Illinois Country.

The magazine (ammunition storehouse) of the fort is believed to be the oldest surviving building in Illinois. A partial reconstruction now exists of the limestone fort and the site is preserved as an Illinois state park, four miles (6 km) west of Prairie du Rocher in Randolph County, Illinois. Located on the floodplain area that became known as the American Bottom, the site is south of modern St. Louis. The forts were placed on the National Register of Historic Places and recognized as a National Historic Landmark on October 15, 1966. It was named one of the contributing properties to the French Colonial Historic District in 1974, along with other French-influenced sites such as the Creole House, the Pierre Menard House, the Kolmer Site (a former Indian village), and the site of Fort Kaskaskia.

Historic districts in the United States are designated historic districts recognizing a group of buildings, archaeological resources, or other properties as historically or architecturally significant. Buildings, structures, objects, and sites within a historic district are normally divided into two categories, contributing and non-contributing. Districts vary greatly in size and composition: a historic district could comprise an entire neighborhood with hundreds of buildings, or a smaller area with just one or a few resources.

Historic districts can be created by federal, state, or local governments. At the federal level, they are designated by the National Park Service and listed on the National Register of Historic Places; this is a largely honorary designation that does not restrict what property owners may do with a property. State-level historic districts usually do not include restrictions, though this depends on the state. Historic districts created by local municipalities, however, almost always protect historic properties by regulating alterations, demolition, or new construction within the district.

Ohio Drive is a street in Southwest Washington, D.C., located in East and West Potomac Parks and bordering the Tidal Basin, Washington Channel, and the Potomac River. It is a central organizing feature of East Potomac Park, providing the only major vehicular route to and through the area. Unlike most roadways named after states in the District of Columbia, Ohio Drive is not an avenue, nor it is heavily used like Wisconsin or Rhode Island Avenues. However, the segment from Independence Avenue to the Rock Creek and Potomac Parkway is an important commuter route.

Ohio Drive SW is a contributing property to the East and West Potomac Parks Historic District, which was listed on the National Register of Historic Places in November 1973.

The New York State Capitol, the seat of the New York state government, is located in Albany, the capital city of the U.S. state of New York. The capitol building is part of the Empire State Plaza complex on State Street in Capitol Park. Housing the New York State Legislature, the building was completed in 1899 at a cost of US$25 million (equivalent to $794 million in modern dollars), making it the most expensive government building of its time. It was listed on the National Register of Historic Places in 1971, then included as a contributing property when the Lafayette Park Historic District was listed in 1978. The New York State Capitol was declared a National Historic Landmark in 1979.

The New York Court of Appeals Building, officially referred to as Court of Appeals Hall, is located at the corner of Eagle and Pine streets in central Albany, New York, United States. It is a stone Greek Revival building built in 1842 from a design by Henry Rector. In 1971 it was listed on the National Register of Historic Places, one of seven buildings housing a state's highest court currently so recognized. Seven years later it was included as a contributing property when the Lafayette Park Historic District was listed on the Register.

When built it was known as the State Hall, housing not the court (which sat in the state capitol) but its clerks. In addition to them, it was the offices of several other officials of the state's executive branch. Four years after its completion, a new state constitution was adopted, uniting two separate court hierarchies into one with the Court of Appeals as the highest court in the state.

The Chicago Water Tower is a contributing property and landmark in the Old Chicago Water Tower District in Chicago, Illinois, United States, that is listed on the National Register of Historic Places. Built to enclose the tall machinery of a powerful water pump in 1869, it became particularly well known when it survived the Great Chicago Fire of 1871, although adjacent buildings burned to the ground.

The large urban, mixed-use development Water Tower Place was named after this water tower.
