Greenwich in the context of "GMT"

The Eastern Hemisphere is the half of the planet Earth which is east of the prime meridian (which crosses Greenwich, London, United Kingdom) and west of the antimeridian (which crosses the Pacific Ocean and relatively little land from pole to pole). It is also used to refer to Afro-Eurasia (Africa and Eurasia) and Australia, in contrast with the Western Hemisphere, which includes mainly North and South America. The Eastern Hemisphere may also be called the "Oriental Hemisphere", and may in addition be used in a cultural or geopolitical sense as a synonym for the European term, "Old World."

Henry VIII (28 June 1491 – 28 January 1547) was King of England from 22 April 1509 until his death in 1547. Henry was a dominant and forceful monarch. He is also known for his six marriages and his efforts to have his first marriage, to Catherine of Aragon, annulled. His disagreement with Pope Clement VII about such an annulment led Henry to initiate the English Reformation, separating the Church of England from papal authority. He appointed himself Supreme Head of the Church of England and dissolved convents and monasteries, for which he was excommunicated by the pope.

Born in Greenwich, Henry brought radical changes to the Constitution of England, expanding royal power and ushering in the theory of the divine right of kings in opposition to papal supremacy. He frequently used charges of treason and heresy to quell dissent, and those accused were often executed without a formal trial using bills of attainder. He achieved many of his political aims through his chief ministers, some of whom were banished or executed when they fell out of his favour. Thomas Wolsey, Thomas More, Thomas Cromwell, and Thomas Cranmer all figured prominently in his administration.

The Greenwich meridian is a prime meridian, a geographical reference line that passes through the Royal Observatory, Greenwich, in London, England. From 1884 to 1974, the Greenwich meridian was the international standard prime meridian, used worldwide for timekeeping and navigation. The modern standard, the IERS Reference Meridian, is based on the Greenwich meridian, but differs slightly from it. This prime meridian (at the time, one of many) was first established by Sir George Airy (in 1851). In 1883, the International Geodetic Association formally recommended to governments that the meridian through Greenwich be adopted as the international standard prime meridian. In October of the following year, at the invitation of the President of the United States, 41 delegates from 25 nations met in Washington, D.C., United States, for the International Meridian Conference. This inter-governmental conference selected the meridian passing through Greenwich as the world standard prime meridian. However, France abstained from the vote, and French maps continued to use the Paris meridian for several decades. In the 18th century, London lexicographer Malachy Postlethwayt published his African maps showing the "Meridian of London" intersecting the Equator a few degrees west of the later meridian and Accra, Ghana.

In art history, the French term objet d'art (/ˌɒbʒeɪ ˈdɑːr/ ; French pronunciation: [ɔbʒɛ daʁ]) describes an ornamental work of art, and the term objets d’art describes a range of works of art, usually small and three-dimensional, made of high-quality materials, and a finely-rendered finish that emphasises the aesthetics of the artefact. Artists create and produce objets d’art in the fields of the decorative arts and metalwork, porcelain and vitreous enamel; figurines, plaquettes, and engraved gems; ivory carvings and semi-precious hardstone carvings; tapestries, antiques, and antiquities; and books with fine bookbinding.

The National Maritime Museum, Greenwich, London, describes their accumulated artworks as a: "collection of objets d’art [which] comprises over 800 objects. These are mostly small, decorative art items that fall outside the scope of the Museum’s ceramic, plate, textiles and glass collections." The artwork collection also includes metal curtain ties, a lacquered papier-maché tray, tobacco boxes, cigarette cases, découpage (cut-paper items), portrait miniatures, a gilt-brass clock finial, plaques, statuettes, plaquettes, a horse brass, a metal pipe tamper, a small glass painting, et cetera.

The Palace of Placentia, also known as Greenwich Palace,was an English royal residence that was initially built by Prince Humphrey, Duke of Gloucester, in 1443. Over the centuries it took several different forms, until it was turned into a hospital in the 1690s. The palace was a place designed for pleasure, entertainment and an escape from the city. It was located at Greenwich on the south bank of the River Thames, downstream from London.

On a hill behind his palace, the duke built Duke Humphrey's Tower, later known as Greenwich Castle; the "castle" was subsequently demolished to make way for the Royal Observatory, Greenwich, which survives. The original river-side residence was extensively rebuilt around 1500 by King Henry VII. A detached residence, the Queen's House, was built on the estate in the early 1600s and also survives. In 1660, the old main palace was demolished by Charles II to make way for a proposed new palace, which was only partly constructed in the east wing. Nearly forty years later, at the behest of Queen Mary II, the Greenwich Hospital (now called the Old Royal Naval College) remodelled this wing, expanded, and rebuilt on the site.
