Moat in the context of Dam

Edo Castle (江戸城, Edo-jō) is a flatland castle that was built in 1457 by Ōta Dōkan in Edo, Toshima District, Musashi Province. In modern times it is part of the Tokyo Imperial Palace in Chiyoda, Tokyo, and is therefore also known as Chiyoda Castle (千代田城, Chiyoda-jō).Tokugawa Ieyasu established the Tokugawa shogunate there, and it was the residence of the shōgun and the headquarters of the military government during the Edo period (1603–1867) in Japanese history. After the resignation of the shōgun and the Meiji Restoration, it became the Tokyo Imperial Palace. Some moats, walls and ramparts of the castle survive to this day. However, the grounds were more extensive during the Edo period, with Tokyo Station and the Marunouchi section of the city lying within the outermost moat. It also encompassed Kitanomaru Park, the Nippon Budokan Hall and other current landmarks of the surrounding area.

The fortifications of the town of Rhodes are shaped like a defensive crescent around the medieval town and consist mostly of a fortification composed of a huge wall made of an embankment encased in stone, equipped with scarp, bastions, moat, counterscarp and glacis. The portion of fortifications facing the harbour is instead composed of a crenellated wall. On the moles, towers and defensive forts are found.

They were built by the Knights Hospitaller of Saint John by enhancing the existing Byzantine walls starting from 1309, the year in which they took possession of the island after a three-year struggle.

Angkor Wat (/ˌæŋkɔːr ˈwɒt/; Khmer: អង្គរវត្ត, "City/Capital of Temples") is a Hindu-Buddhist complex in Cambodia. Located on a site measuring 162.6 hectares (1.6 km; 401.8 acres) within the ancient Khmer capital city of Angkor, it was originally constructed in 1150 CE as a Hindu temple dedicated to the deity Vishnu. It was later gradually transformed into a Buddhist temple towards the end of the century. Hailed as the largest religious structure in the world, it is one of the best examples of Khmer architecture and a symbol of Cambodia, depicted as a part of the Cambodian national flag.

Angkor Wat was built at the behest of the Khmer king Suryavarman II in the early 12th century in Yaśodharapura (present-day Angkor), the capital of the Khmer Empire, as his state temple and eventual mausoleum. Angkor Wat combines two basic plans of Khmer temple architecture: the temple-mountain and the later galleried temple. It is designed to represent Mount Meru, home of the devas in Hindu mythology and is surrounded by a moat more than 5 km (3.1 mi). Enclosed within an outer wall 3.6 kilometres (2.2 mi) long are three rectangular galleries, each raised above the next. The expansive Temple complex covers an area of 400 acres. At the centre of the temple stands a quincunx of towers. Unlike most Angkorian temples, Angkor Wat is oriented to the west with scholars divided as to the significance of this.

The Tower of London, officially His Majesty's Royal Palace and Fortress of the Tower of London, is a historic citadel and castle on the north bank of the River Thames in London, England. It lies within the London Borough of Tower Hamlets, which is separated from the eastern edge of the square mile of the City of London by the open space known as Tower Hill. It was founded toward the end of 1066 as part of the Norman Conquest. The White Tower, which gives the entire castle its name, was built by William the Conqueror in 1078 and was initially a resented symbol of oppression, inflicted upon London by the new Norman ruling class. The castle was also used as a prison from 1100 (Ranulf Flambard, Bishop of Durham) until 1952 (the Kray twins), although that was not its primary purpose. A grand palace early in its history, it served as a royal residence. As a whole, the Tower is a complex of several buildings set within two concentric rings of defensive walls and a moat. There were several phases of expansion, mainly under kings Richard I, Henry III, and Edward I in the 12th and 13th centuries. The general layout established by the late 13th century remains despite later activity on the site.

The Tower of London has played a prominent role in English history. It was besieged several times, and controlling it has been important to controlling the country. The Tower has served variously as an armoury, a treasury, a menagerie, the home of the Royal Mint, a public record office, and the home of the Crown Jewels of England. From the early 14th century until the reign of Charles II in the 17th century, the monarch would traditionally prepare for several nights at the Tower, and lead a procession from there to Westminster Abbey for their coronation. In the absence of the monarch, the Constable of the Tower was in charge of the castle. This was a powerful and trusted position in the medieval period. In the late 15th century, the Princes in the Tower were housed at the castle when they mysteriously disappeared, presumed murdered. Under the Tudors, the Tower was used less as a royal residence, and despite attempts to refortify and repair the castle, its defences lagged behind developments to deal with artillery.

A drawbridge or draw-bridge is a type of moveable bridge typically at the entrance to a castle or tower surrounded by a moat. In some forms of English, including American English, the word drawbridge commonly refers to all types of moveable bridges, such as bascule bridges, vertical-lift bridges and swing bridges, but this article concerns the narrower historical definition where the bridge is used in a defensive structure.

As used in castles or defensive structures, drawbridges provide access across defensive structures when lowered, but can quickly be raised from within to deny entry to an enemy force.

A scarp and a counterscarp are the inner and outer sides, respectively, of a ditch or moat used in fortifications. Attackers (if they have not bridged the ditch) must descend the counterscarp and ascend the scarp. In permanent fortifications, the scarp and counterscarp may be encased in stone. In less permanent fortifications, the counterscarp may be lined with paling fence set at an angle so as to give no cover to the attackers, but to make advancing and retreating more difficult.

If an attacker succeeds in breaching a wall, a coupure can be dug on the inside of the wall to hinder the forlorn hope, in which case the side of the ditch furthest from the breached wall and closest to the centre of the fortification is also called the counterscarp.

A water castle, sometimes water-castle, is a castle which incorporates a natural or artificial body of water into its defences. It can be entirely surrounded by water-filled moats (moated castle) or natural waterbodies such as island castles in a river or offshore. The term comes from European castle studies, mainly German Burgenkunde. Some interpretations of the category emphasise that the use of water extends beyond a defensive purpose. When stately homes were built in such a location, or a Wasserburg was later rebuilt as a residential manor, the German term becomes Wasserschloss, lit. "water palace/manor".

A lord of the manor, in Anglo-Saxon England and Norman England, is the landholder of a rural estate. The titles date to the English feudal (specifically baronial) system. The lord enjoyed manorial rights (the rights to establish and occupy a residence, known as the manor house and demesne) as well as seignory, the right to grant or draw benefit from the estate (for example, as a landlord). The title is not a peerage or title of upper nobility (although the holder could also be a peer) but was a relationship to land and how it could be used and those living on the land (tenants) may be deployed, and the broad estate and its inhabitants administered. The title continues in modern England and Wales as a legally recognised form of property that can be held independently of its historical rights. It may belong entirely to one person or be a moiety shared with other people. The title is known as Breyr in Welsh.

In the British Crown Dependencies of Jersey and Guernsey the equivalent title is Seigneur.

Imphal (Meitei: [im.pʰal]; English: UK: /ˈɪmfəl/, US: /ˈɪmpˌhʌl/) is the capital city of the Indian state of Manipur. The metropolitan centre of the city contains the ruins of Kangla Palace (officially known as Kangla Fort), the royal seat of the former Kingdom of Manipur, surrounded by a moat. Spread over parts of the districts of Imphal West and Imphal East, the former contains the majority of the city's area and population. Imphal is part of the Smart Cities Mission under the Ministry of Housing and Urban Affairs. Being a mega commercial hub, Imphal is known for its weaving, brass-ware, bronze-ware, and other cottage industries. Meitei language (officially known as Manipuri language) is the most widely spoken language in the city.

INS Imphal, the third ship of the Visakhapatnam-class stealth guided missile destroyer of the Indian Navy, was named in recognition of the Indian soldiers who fought in Battle of Imphal during World War II, and is the first Indian Navy Ship (INS) named after a city in Northeast India.

The British Embassy, Tokyo (駐日英国大使館 Chūnichi Eikoku Taishikan) is the chief diplomatic mission of the United Kingdom in Japan, with the Ambassador of the United Kingdom to Japan being the chief of mission. The embassy compound measures about 35,000 m, located at No 1 Ichibanchō, Chiyoda-ku, Tokyo (Japanese: 東京都千代田区一番町一), to the west of the Imperial Palace, and separated from the latter by a moat.

The Sint-Jansbeek (Dutch pronunciation: [sɪɲˈtɕɑnzbeːk]) is a stream in Arnhem, which streams down from the hills of Zijpendaal through the Sonsbeek park and the inner city of Arnhem to the river Rhine. The Sint-Jansbeek has always been an open stream, but the part in the inner city is covered since the city moats were filled in the 19th century. The stream from the source in Zijpendaal through the park Sonsbeek is still open.

Bodiam Castle (/ˈboʊdiəm/) is a 14th-century moated castle near Robertsbridge in East Sussex, England. It was built in 1385 by Sir Edward Dalyngrigge, a former knight of Edward III, with the permission of Richard II, ostensibly to defend the area against French invasion during the Hundred Years' War. Of quadrangular plan, Bodiam Castle has no keep, having its various chambers built around the outer defensive walls and inner courts. Its corners and entrance are marked by towers, and topped by crenellations. Its structure, details and situation in an artificial watery landscape indicate that display was an important aspect of the castle's design as well as defence. It was the home of the Dalyngrigge family and the centre of the manor of Bodiam.

Possession of Bodiam Castle passed through several generations of Dalyngrigges, until their line became extinct when the castle passed by marriage to the Lewknor family. During the Wars of the Roses, Sir Thomas Lewknor supported the House of Lancaster, and when Richard III of the House of York became king in 1483, a force was despatched to besiege Bodiam Castle. It is unrecorded whether the siege went ahead, but it is thought that Bodiam surrendered without much resistance. The castle was confiscated, but returned to the Lewknors when Henry VII of the House of Tudor became king in 1485. Descendants of the Lewknors owned the castle until at least the 16th century.

A fence is a structure that encloses an area, typically outdoors creating a boundary, and is usually constructed from posts that are connected by boards, wire, rails or netting. A fence differs from a wall in not having a solid foundation along its whole length.

Alternatives to fencing include a ditch (sometimes filled with water, forming a moat).

Chitralada Royal Villa (Thai: พระตำหนักจิตรลดารโหฐาน; RTGS: Chit Lada Raho-than) is a royal villa located within Dusit Palace. This villa was permanent-residence of King Bhumibol Adulyadej (Rama IX), the longest-serving monarch of Thailand and Queen Sirikit. He moved there after the death of his older brother, King Rama VIII in the Grand Palace. The palace grounds, which are surrounded by a moat and guarded by the royal guards, also contain the Chitralada School, initially established for the children of the royal family and palace staff. Chitralada Royal Villa has a Chitralada railway station which served for the royal family who lived in the villa. Prince Dipangkorn Rasmijoti was a pupil in the Chitralada School, the school is considered the most exclusive in Thailand.

Queen Mother Sirikit resided in the palace until her death in October 2025.

Oxford Castle is a large, partly ruined medieval castle on the western side of central Oxford in Oxfordshire, England. Most of the original moated, wooden motte and bailey castle was replaced in stone in the late 12th or early 13th century and the castle played an important role in the conflict of the Anarchy. In the 14th century the military value of the castle diminished and the site became used primarily for county administration and as a prison. The surviving rectangular St George's Tower is now believed to pre-date the remainder of the castle and be a watch tower associated with the original Saxon west gate of the city.

Most of the castle was destroyed in the English Civil War and by the 18th century the remaining buildings had become Oxford's local prison. A new prison complex was built on the site from 1785 onwards and expanded in 1876; this became HM Prison Oxford.

A courtyard house is a type of house—often a large house—where the main part of the building is disposed around a central courtyard. Many houses that have courtyards are not courtyard houses of the type covered by this article. For example, large houses often have small courtyards surrounded by service rooms or corridors, but the main rooms are not disposed around a courtyard. Blenheim Palace in England is an example of such a house.

The main rooms of a courtyard house often open onto the courtyard, and the exterior walls may be windowless and/or semi-fortified and/or surrounded by a moat. Courtyard houses of this type occupy an intermediate position between a castle or fortress, where defence is the primary design consideration, and more modern plans in which defence is not a consideration at all. In England the courtyard house was a popular design for large houses in the sixteenth century, after noblemen had stopped building themselves castles, but before thoughts of defence were altogether forgotten in the planning of country houses.

Tilbury Fort, also known historically as the Thermitage Bulwark and the West Tilbury Blockhouse, is an artillery fort on the north bank of the River Thames in England. The earliest version of the fort, comprising a small blockhouse with artillery covering the river, was constructed by King Henry VIII to protect London against attack from France as part of his Device programme. It was reinforced during the 1588 Spanish Armada invasion scare, after which it was reinforced with earthwork bastion, and Parliamentary forces used it to help secure the capital during the English Civil War of the 1640s. Following naval raids during the Anglo-Dutch Wars, the fort was enlarged by Sir Bernard de Gomme from 1670 onwards to form a star-shaped defensive work, with angular bastions, water-filled moats and two lines of guns facing onto the river.

In addition to protecting the Thames, in the 18th century Tilbury also began to be used as a transit depot and for storing gunpowder. It continued to be essential for the defence of the capital and a new artillery battery was added in the south-east corner during the Napoleonic Wars. The fort became decreasingly significant as a defensive structure as military technology developed in the 19th century. It was redeveloped to hold heavy artillery after 1868, providing a second line of defence along the river, but further changes in technology meant that it had become obsolete by the end of the century. Instead Tilbury became a strategic depot, forming a logistical hub for storing and moving troops and materiel throughout the First World War. The fort had only a limited role in the Second World War and was demobilised in 1950.
