Zwinger
A () is an open kill zone area between two defensive walls that is used for defensive purposes. s were built in the medieval and early modern periods to improve the defence of castles and town walls. The term is usually left untranslated, but is sometimes rendered as "outer courtyard", presumably referring to the subsequent role of a as a castle's defences became redundant and it was converted into a palace or ''schloss''; however, this belies its original purpose as a form of killing ground for the defence. The word is linked with , "to force", perhaps because the forced an enemy to negotiate it before assaulting the main defensive line. Essenwein states that the "main purpose of this feature was so that the besieging force could not reach the actual castle wall very easily with battering rams or belfries, but had to stop at the lower, outer wall; also that two ranks of archers, behind and above one another, could fire upon the approaching enemy".von Essenwein, "Kriegsba ...

Zwinger, Dresden
The Zwinger (, ) is a palatial complex with gardens in Dresden, Germany. Designed by architect Matthäus Daniel Pöppelmann, it is one of the most important buildings of the Baroque period in Germany. Along with the Frauenkirche, the Zwinger is the most famous architectural monument of Dresden. The name "Zwinger" goes back to the name used in the Middle Ages for a fortress part between the outer and inner fortress walls, even though the Zwinger no longer had a function corresponding to the name at the start of construction. The Zwinger was built in 1709 as an orangery and garden as well as a representative festival area. Its richly decorated pavilions and the galleries lined with balustrades, figures and vases testify to the splendor during the reign of Augustus the Strong, Elector of Saxony and elected King of Poland. In the original conception of the elector, the Zwinger was the forecourt of a new castle that would take up the area between it and the Elbe; therefore, th ...

Fortezza Di Carcassonne - Interno-1
Fortezza is an information security system that uses the Fortezza Crypto Card, a PC Card-based security token. It was developed for the U.S. government's Clipper chip project and has been used by the U.S. Government in various applications. Each individual who is authorized to see protected information is issued a ''Fortezza card'' that stores public key, private keys and other data needed to gain access. It contains an NSA approved security microprocessor called ''Capstone (cryptography), Capstone'' (MYK-80) that implements the Skipjack (cipher), Skipjack encryption algorithm. The original Fortezza card (KOV-8) is a Type 2 encryption, Type 2 product which means it cannot be used for classified information. The most widely used Type 1 encryption card is the KOV-12 Fortezza card which is used extensively for the Defense Message System (DMS). The KOV-12 is cleared up to TOP SECRET/SCI. A later version, called KOV-14 or Fortezza Plus, uses a Krypton microprocessor that implements ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gate Tower
A gate tower is a tower built over or next to a major gateway. Usually it is part of a medieval fortification. This may be a town or city wall, fortress, castle or castle chapel. The gate tower may be built as a twin tower on either side of an entranceway. Even in the design of modern building complexes, gate towers may be constructed symbolically as a main entrance. The gate tower can also stand as a twin tower on both sides of a gate system. Gate towers are also used symbolically as the main entrance in the design of modern building complexes. The Kasselburg in Rhineland-Palatinate has a double tower gate tower, which was also used as a residential tower.

Early Medieval
The Early Middle Ages (or early medieval period), sometimes controversially referred to as the Dark Ages, is typically regarded by historians as lasting from the late 5th to the 10th century. They marked the start of the Middle Ages of European history, following the decline of the Western Roman Empire, and preceding the High Middle Ages ( 11th to 14th centuries). The alternative term ''late antiquity'', for the early part of the period, emphasizes elements of continuity with the Roman Empire, while ''Early Middle Ages'' is used to emphasize developments characteristic of the earlier medieval period. The period saw a continuation of trends evident since late classical antiquity, including population decline, especially in urban centres, a decline of trade, a small rise in average temperatures in the North Atlantic region and increased migration. In the 19th century the Early Middle Ages were often labelled the ''Dark Ages'', a characterization based on the relative scarci ...

Constantinople
Constantinople (#Names of Constantinople, see other names) was a historical city located on the Bosporus that served as the capital of the Roman Empire, Roman, Byzantine Empire, Byzantine, Latin Empire, Latin, and Ottoman Empire, Ottoman empires between its consecration in 330 until 1930, when it was renamed to Istanbul. Initially as New Rome, Constantinople was founded in 324 during the reign of Constantine the Great on the site of the existing settlement of Byzantium, and shortly thereafter in 330 became the capital of the Roman Empire. Following the collapse of the Western Roman Empire in the late 5th century, Constantinople remained the capital of the Eastern Roman Empire (also known as the Byzantine Empire; 330–1204 and 1261–1453), the Latin Empire (1204–1261), and the Ottoman Empire (1453–1922). Following the Turkish War of Independence, the Turkish capital then moved to Ankara. Although the city had been known as Istanbul since 1453, it was officially renamed as Is ...

Theodosian Walls
The Walls of Constantinople (; ) are a series of defensive wall, defensive stone walls that have surrounded and protected the city of Constantinople (modern Fatih district of Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of ancient history, antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world. Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger. They saved the city, and the Byzantine Empire with ...

Stable
A stable is a building in which working animals are kept, especially horses or oxen. The building is usually divided into stalls, and may include storage for equipment and feed. Styles There are many different types of stables in use today; the American-style stable called a barn, for instance, is a large barn with a door at each end and individual stalls inside or free-standing stables with top and bottom-opening doors. The term "stable" is additionally utilised to denote a business or a collection of animals under the care of a single owner, irrespective of their housing or whereabouts. A building with tie stalls is also known as stanchion or stall barn, where animals are tethered by the head or neck to their stall. It is mostly used in the dairy cow industry, but traditionally horses were also tied up. The exterior design of a stable can vary widely based on climate, building materials, historical period and cultural styles of architecture. A wide range of building ...

Barn
A barn is an agricultural building usually on farms and used for various purposes. In North America, a barn refers to structures that house livestock, including cattle and horses, as well as equipment and fodder, and often grain.Allen G. Noble, ''Traditional Buildings: A Global Survey of Structural Forms and Cultural Functions'' (New York: Tauris, 2007), 30. As a result, the term barn is often qualified e.g. tobacco barn, dairy barn, cow house, sheep barn, potato barn. In the British Isles, the term barn is restricted mainly to storage structures for unthreshed cereals and fodder, the terms byre or shippon being applied to cow shelters, whereas horses are kept in buildings known as stables. In mainland Europe, however, barns were often part of integrated structures known as byre-dwellings (or housebarns in US literature). In addition, barns may be used for equipment storage, as a covered workplace, and for activities such as threshing. Etymology The word ''barn'' c ...

Garden
A garden is a planned space, usually outdoors, set aside for the cultivation, display, and enjoyment of plants and other forms of nature. The single feature identifying even the wildest wild garden is ''control''. The garden can incorporate both natural and artificial materials. Gardens often have design features including statuary, follies, pergolas, trellises, stumperies, dry creek beds, and water features such as fountains, ponds (with or without fish), waterfalls or creeks. Some gardens are for ornamental purposes only, while others also produce food crops, sometimes in separate areas, or sometimes intermixed with the ornamental plants. Food-producing gardens are distinguished from farms by their smaller scale, more labor-intensive methods, and their purpose (enjoyment of a pastime or self-sustenance rather than producing for sale, as in a market garden). Flower gardens combine plants of different heights, colors, textures, and fragrances to create interest and deli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal
Animals are multicellular, eukaryotic organisms in the Biology, biological Kingdom (biology), kingdom Animalia (). With few exceptions, animals heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, have myocytes and are motility, able to move, can reproduce sexually, and grow from a hollow sphere of Cell (biology), cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million extant taxon, living animal species have been species description, described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and biological interaction, interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as ...

Firearm
A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and operated by an individual. The term is legally defined further in different countries (see legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other explosive propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stabili ...
