Roosevelt Hall (National War College)
Roosevelt Hall (1903–1907) is an immense Beaux Arts-style building housing the National War College on Fort Lesley J. McNair, Washington, DC, USA. The original home of the Army War College (1907–1946), it is now designated a National Historical Landmark (1972) and listed on the National Register of Historic Places (1972). History Roosevelt Hall was originally built as the central focus of enormous complex envisioned by President Theodore Roosevelt and Secretary of War Elihu Root to house a General Staff School for senior U.S. Army officers. The historic Washington Arsenal (which became Fort McNair in 1948) was selected as the site. Between 1901 and 1903, the early 19th-century arsenal buildings were razed to make way for the projected complex. As many as fifty additional buildings were envisioned, including barracks, mess halls, and faculty quarters, but only Roosevelt Hall was completed and the ambitious plan was never realized in its entirety. The cornerstone for Rooseve ...

Department Of State
The United States Department of State (DOS), or State Department, is an executive department of the U.S. federal government responsible for the country's foreign policy and relations. Equivalent to the ministry of foreign affairs of other nations, its primary duties are advising the U.S. president on international relations, administering diplomatic missions, negotiating international treaties and agreements, and representing the United States at the United Nations conference. Established in 1789 as the first administrative arm of the U.S. executive branch, the State Department is considered among the most powerful and prestigious executive agencies. It is headed by the secretary of state, who reports directly to the U.S. president and is a member of the Cabinet. Analogous to a foreign minister, the secretary of state serves as the federal government's chief diplomat and representative abroad, and is the first Cabinet official in the order of precedence and in the presiden ...

Pediment
Pediments are gables, usually of a triangular shape. Pediments are placed above the horizontal structure of the lintel, or entablature, if supported by columns. Pediments can contain an overdoor and are usually topped by hood moulds. A pediment is sometimes the top element of a portico. For symmetric designs, it provides a center point and is often used to add grandness to entrances. The tympanum, the triangular area within the pediment, is often decorated with a pedimental sculpture which may be freestanding or a relief sculpture. The tympanum may hold an inscription, or in modern times, a clock face. Pediments are found in ancient Greek architecture as early as 600 BC (e.g. the archaic Temple of Artemis). Variations of the pediment occur in later architectural styles such as Classical, Neoclassical and Baroque. Gable roofs were common in ancient Greek temples with a low pitch (angle of 12.5° to 16°). History The pediment is found in classical Greek temples, Et ...

Pavilion
In architecture, ''pavilion'' has several meanings: * It may be a subsidiary building that is either positioned separately or as an attachment to a main building. Often it is associated with pleasure. In palaces and traditional mansions of Asia, there may be pavilions that are either freestanding or connected by covered walkways, as in the Forbidden City ( Chinese pavilions), Topkapi Palace in Istanbul, and in Mughal buildings like the Red Fort. * As part of a large palace, pavilions may be symmetrically placed building ''blocks'' that flank (appear to join) a main building block or the outer ends of wings extending from both sides of a central building block, the ''corps de logis''. Such configurations provide an emphatic visual termination to the composition of a large building, akin to bookends. The word is from French (Old French ) and it meant a small palace, from Latin (accusative of ). In Late Latin and Old French, it meant both ‘butterfly’ and ‘tent’, becaus ...

Dome
A dome () is an architectural element similar to the hollow upper half of a sphere. There is significant overlap with the term cupola, which may also refer to a dome or a structure on top of a dome. The precise definition of a dome has been a matter of controversy and there are a wide variety of forms and specialized terms to describe them. A dome can rest directly upon a Rotunda (architecture), rotunda wall, a Tholobate, drum, or a system of squinches or pendentives used to accommodate the transition in shape from a rectangular or square space to the round or polygonal base of the dome. The dome's apex may be closed or may be open in the form of an Oculus (architecture), oculus, which may itself be covered with a roof lantern and cupola. Domes have a long architectural lineage that extends back into prehistory. Domes were built in ancient Mesopotamia, and they have been found in Persian architecture, Persian, Ancient Greek architecture, Hellenistic, Ancient Roman architecture, ...

Greensward
A grassland is an area where the vegetation is dominated by grasses ( Poaceae). However, sedge ( Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures." (Pilot Assessment of Global Ecosystems, 2000) * ...

Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Brick
A brick is a type of block used to build walls, pavements and other elements in masonry construction. Properly, the term ''brick'' denotes a block composed of dried clay, but is now also used informally to denote other chemically cured construction blocks. Bricks can be joined using mortar, adhesives or by interlocking them. Bricks are usually produced at brickworks in numerous classes, types, materials, and sizes which vary with region and time period, and are produced in bulk quantities. ''Block'' is a similar term referring to a rectangular building unit composed of similar materials, but is usually larger than a brick. Lightweight bricks (also called lightweight blocks) are made from expanded clay aggregate. Fired bricks are one of the longest-lasting and strongest building materials, sometimes referred to as artificial stone, and have been used since circa 4000 BC. Air-dried bricks, also known as mud-bricks, have a history older than fired bricks, and have an additi ...

Neoclassical Architecture
Neoclassical architecture is an architectural style produced by the Neoclassical movement that began in the mid-18th century in Italy and France. It became one of the most prominent architectural styles in the Western world. The prevailing styles of architecture in most of Europe for the previous two centuries, Renaissance architecture and Baroque architecture, already represented partial revivals of the Classical architecture of ancient Rome and (much less) ancient Greek architecture, but the Neoclassical movement aimed to strip away the excesses of Late Baroque and return to a purer and more authentic classical style, adapted to modern purposes. The development of archaeology and published accurate records of surviving classical buildings was crucial in the emergence of Neoclassical architecture. In many countries, there was an initial wave essentially drawing on Roman architecture, followed, from about the start of the 19th century, by a second wave of Greek Revival architec ...

McKim, Mead And White
McKim, Mead & White was an American architectural firm that came to define architectural practice, urbanism, and the ideals of the American Renaissance in fin de siècle New York. The firm's founding partners Charles Follen McKim (1847–1909), William Rutherford Mead (1846–1928) and Stanford White (1853–1906) were giants in the architecture of their time, and remain important as innovators and leaders in the development of modern architecture worldwide. They formed a school of classically trained, technologically skilled designers who practiced well into the mid-twentieth century. According to Robert A. M. Stern, only Frank Lloyd Wright was more important to the identity and character of modern American architecture. The firm's New York City buildings include Manhattan's former Pennsylvania Station, the Brooklyn Museum, and the main campus of Columbia University. Elsewhere in New York State and New England, the firm designed college, library, school and other buildings such ...
