A cross is a compound geometrical figure consisting of two intersecting lines, usually perpendicular to each other. The lines usually run vertically and horizontally. A cross of oblique lines, in the shape of the Latin letter X, is termed a saltire in heraldic terminology.
A tailplane, also known as a horizontal stabilizer, is a small lifting surface located on the tail (empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes. Not all fixed-wing aircraft have tailplanes. Canards, tailless and flying wing aircraft have no separate tailplane, while in V-tail aircraft the vertical stabilizer, rudder, and the tail-plane and elevator are combined to form two diagonal surfaces in a V layout.
Cathedrals, collegiate churches, and monastic churches like those of abbeys and priories, often have certain complex structural forms that are found less often in parish churches. They also tend to display a higher level of contemporary architectural style and the work of accomplished craftsmen, and occupy a status both ecclesiastical and social that an ordinary parish church rarely has. Such churches are generally among the finest buildings locally and a source of regional pride. Many are among the world's most renowned works of architecture. These include St Peter's Basilica, Notre-Dame de Paris, Cologne Cathedral, Salisbury Cathedral, Antwerp Cathedral, Prague Cathedral, Lincoln Cathedral, the Basilica of Saint-Denis, Santa Maria Maggiore, the Basilica of San Vitale, St Mark's Basilica, Westminster Abbey, Saint Basil's Cathedral, Antoni Gaudí's incomplete Sagrada Família and the ancient cathedral of Hagia Sophia in Istanbul, now a mosque.
A baptismal font is an ecclesiastical architectural element, which serves as a receptacle for baptismal water used for baptism, as a part of Christian initiation for both rites of infant and adult baptism.
The V-tail or vee-tail of an aircraft is an unconventional arrangement of the tail control surfaces that replaces the traditional vertical and horizontal surfaces with two surfaces set in a V-shaped configuration. It is not widely used in aircraft design. The aft edge of each twin surface is a hinged control surface called a ruddervator, which combines the functions of both a rudder and elevator.
A transept is a transverse part of any building, which lies across the main body of the building. In cruciform ("cross-shaped") churches, in particular within the Romanesque and Gothic Christian church architectural traditions, a transept is an area set crosswise to the nave. Each half of a transept is known as a semitransept.
A Latin cross or crux immissa is a type of cross in which the vertical beam sticks above the crossbeam, giving the cross four arms. Typically the two horizontal and upper vertical arm are the same length, although sometimes the vertical is shorter, however the lower vertical arm is always much longer than any other arm.
The empennage, also known as the tail or tail assembly, is a structure at the rear of an aircraft that provides stability during flight, in a way similar to the feathers on an arrow. The term derives from the French language verb empenner which means "to feather an arrow". Most aircraft feature an empennage incorporating vertical and horizontal stabilising surfaces which stabilise the flight dynamics of yaw and pitch, as well as housing control surfaces.
Church architecture refers to the architecture of Christian buildings, such as churches, chapels, convents, seminaries, etc. It has evolved over the two thousand years of the Christian religion, partly by innovation and partly by borrowing other architectural styles as well as responding to changing beliefs, practices and local traditions. From the Early Christianity to the present, the most significant objects of transformation for Christian architecture and design were the great churches of Byzantium, the Romanesque abbey churches, Gothic cathedrals and Renaissance basilicas with its emphasis on harmony. These large, often ornate and architecturally prestigious buildings were dominant features of the towns and countryside in which they stood. However, far more numerous were the parish churches in Christendom, the focus of Christian devotion in every town and village. While a few are counted as sublime works of architecture to equal the great cathedrals and churches, the majority developed along simpler lines, showing great regional diversity and often demonstrating local vernacular technology and decoration.
The cruciform tail is an aircraft empennage configuration which, when viewed from the aircraft's front or rear, looks much like a cross. The usual arrangement is to have the horizontal stabilizer intersect the vertical tail somewhere near the middle, and above the top of the fuselage. The design is often used to locate the horizontal stabilizer away from jet exhaust, propeller and wing wake, as well as to provide undisturbed airflow to the rudder.
An aircraft stabilizer is an aerodynamic surface, typically including one or more movable control surfaces, that provides longitudinal (pitch) and/or directional (yaw) stability and control. A stabilizer can feature a fixed or adjustable structure on which any movable control surfaces are hinged, or it can itself be a fully movable surface such as a stabilator. Depending on the context, "stabilizer" may sometimes describe only the front part of the overall surface.
Eastern Orthodox church architecture constitutes a distinct, recognizable family of styles among church architectures. These styles share a cluster of fundamental similarities, having been influenced by the common legacy of Byzantine architecture from the Eastern Roman Empire. Some of the styles have become associated with the particular traditions of one specific autocephalous Eastern Orthodox patriarchate, whereas others are more widely used within the Eastern Orthodox Church.
A cross-in-square or crossed-dome plan was the dominant architectural form of middle- and late-period Byzantine churches. It featured a square centre with an internal structure shaped like a cross, topped by a dome.
The Pelikan tail is an experimental tail design for fighter jets. It was originally conceived by Ralph Pelikan, who was hired by McDonnell Aircraft, later worked for McDonnell Douglas after the merger of McDonnell with Douglas and, after another merger, retired from Boeing. The concept was used in the Northrop YF-23 fighter. However, it has been considered or included in design specifications in the McDonnell Douglas BAE Joint Strike fighter (JSF) design which was eliminated before prototype stage
The Holmen Church is a Parish church in central Copenhagen in Denmark, on the street called Holmens Kanal. First built as an anchor forge in 1563, it was converted into a naval church by Christian IV. It is famous for having hosted the wedding between Margrethe II of Denmark, queen of Denmark between 1972 and 2024, and Prince Henrik in 1967. It is the burial site of such notabilities as naval heroes Niels Juel and Peter Tordenskjold, and composer Niels Wilhelm Gade, and contains artwork by, among others, Bertel Thorvaldsen and Karel van Mander.
In music, the cross motif is a motif.
Skien Church is a parish church of the Church of Norway in Skien Municipality in Telemark county, Norway. It is located in the town of Skien. It is the church for the Skien parish which is part of the Skien prosti (deanery) in the Diocese of Agder og Telemark. The red brick church was built in a cruciform design in 1894 using plans drawn up by the architect Hagbarth Martin Schytte-Berg. The church seats about 1,050 people.
An octagonal church has an octagonal architectural plan. The exterior and the interior may be shaped as eight-sided polygon with approximately equal sides or only the nave is eight-sided supplemented by choir and porch attached to the octagon. This architectural plan is found in some 70 churches in Norway. Among these Hospitalskirken in Trondheim is the oldest. This type of church plan spread from the Diocese of Nidaros to other parts of Norway. Virtually all octagonal churches in Norway are constructed as log buildings mostly covered by clapboards. Some of the largest churches in Norway are octagonal and the list includes important cultural heritage monuments such as Trinity Church (Oslo), Sør-Fron Church, and Røros Church.
This is the bright and solemn church room of classicism, whether it is such a large building [as Røros Church] or the modest rural log churches, the interior is covered and interconnected by cheerful colors of the Roccoco in marbling and ceiling. This was our last independent contribution to ecclesiastical architecture.
Church building in Norway began when Christianity was established there around the year 1000. The first buildings may have been post churches erected in the 10th or 11th century, but the evidence is inconclusive. For instance under Urnes Stave Church and Lom Stave Church there are traces of older post churches. Post churches were later replaced by the more durable stave churches. About 1,300 churches were built during the 12th and 13th centuries in what was Norway's first building boom. A total of about 3,000 churches have been built in Norway, although nearly half of them have perished. From 1620 systematic records and accounts were kept although sources prior to 1620 are fragmented. Evidence about early and medieval churches is partly archaeological. The "long church" is the most common type of church in Norway. There are about 1620 buildings recognized as churches affiliated with the Church of Norway. In addition, there are a number of gospel halls belonging to the lay movement affiliated with the Church of Norway as well as churches belonging to other Christian bodies. Until the 20th century, most churches were built from wood. 220 buildings are protected by law, and an additional 765 are listed as valuable cultural heritage.
