WA border barrier is a separation barrier that runs along an international border. Such barriers are typically constructed for border control purposes such as curbing illegal immigration, human trafficking, and smuggling. In cases of a disputed or unclear border, erecting a barrier can serve as a de facto unilateral consolidation of a territorial claim that can supersede formal delimitation.
WThe Bangladesh–India border, known locally as the International Border (IB), is an international border running between Bangladesh and India that demarcates the eight divisions of Bangladesh and the Indian states.
WThe Bangladesh–Myanmar border is the international border between the countries of Bangladesh and Myanmar. The border stretches 270 kilometres, from the tripoint with India in the north, to the Bay of Bengal in the south. About 210 km (130 mi) of the border is fenced, with the government of Myanmar announcing in 2017 that it was planning to fence off the rest of the border.
WThe Berlin Wall was a guarded concrete barrier that physically and ideologically divided Berlin from 1961 to 1989. Construction of the wall was commenced by the German Democratic Republic on 13 August 1961. The Wall cut off West Berlin from surrounding East Germany, including East Berlin. The barrier included guard towers placed along large concrete walls, accompanied by a wide area that contained anti-vehicle trenches, beds of nails and other defenses. The Eastern Bloc portrayed the Wall as protecting its population from fascist elements conspiring to prevent the "will of the people" from building a socialist state in East Germany.
WThe Ceuta border fence forms part of the Morocco–Spain border at Ceuta, a city on the North African coast. Constructed by Spain, its purpose is to prevent smuggling and to stop migrants from entering Europe. Morocco objected to the construction of the barrier since it does not recognize Spanish sovereignty in Ceuta.
WThe Egypt–Gaza barrier refers to the steel border barrier along the border between Egypt and the Gaza Strip. Because it is essentially splitting the city of Rafah, the steel barrier is also referred as a separation wall.
WThe Egypt–Israel barrier refers to a border barrier built by Israel along its border with Egypt. It was originally an attempt to curb the influx of illegal migrants from African countries. Construction was approved on 12 January 2010 and began on 22 November 2010. However, following increased insurgent movement across the southern border in 2011 in wake of the crisis in Egypt, Israel upgraded the steel barrier project to include cameras, radar, and motion detectors. In January 2013, construction of the barrier was completed in its main section. The final section of the fence was completed in December 2013.
WThe Fortifications of Derbent are one of the fortified defense lines built by the Persian Sasanian Empire to protect the eastern passage of the Caucasus Mountains against the attacks of the nomadic peoples of the Pontic–Caspian steppe. Built in the 6th century during the reign of Persian emperor Khosrow I and maintained by various later Arab, Turkish and Persian regimes, the fortifications comprise three distinct elements: the citadel of Naryn-Kala at Derbent, the twin long walls connecting it with the Caspian Sea in the east, and the "mountain wall" of Dagh-Bary, running from Derbent to the Caucasus foothills in the west. The immense wall, with a height of up to twenty meters and a thickness of about 10 feet, stretched for forty kilometers between the Caspian Sea and the Caucasus Mountains, thirty north-looking towers stretched for forty kilometers between the Caspian Sea and the Caucasus Mountains, effectively blocking the passage across the Caucasus. The fortification complex was made a UNESCO World Heritage Site in 2003.

WThe Great Wall of China is a series of fortifications that were built across the historical northern borders of ancient Chinese states and Imperial China as protection against various nomadic groups from the Eurasian Steppe. Several walls were built from as early as the 7th century BC, with selective stretches later joined together by Qin Shi Huang (220–206 BC), the first emperor of China. Little of the Qin wall remains. Later on, many successive dynasties have built and maintained multiple stretches of border walls. The most well-known sections of the wall were built by the Ming dynasty (1368–1644).

WThe Iran–Pakistan border is the international border between Iran and Pakistan, demarcating Pakistan's Balochistan province from Iran's Sistan and Balochistan Province; it is 959 kilometres in length. Since circa 2007 Iran has started constructing a border barrier as a replacement for an intermittent tattered border fence.
WThe Iraq–Saudi Arabia border is 811 km in length and runs from the tripoint with Jordan in the west to the tripoint with Kuwait in the east.
WThe Israel−Gaza security barrier is a border barrier first constructed by Israel in 1994 between the Gaza Strip and Israel. The barrier runs along the entire land border of the Gaza Strip. Entry into the Gaza Strip by land is through five crossing points: the northern Erez Crossing into Israel, the southern Rafah Crossing into Egypt, the eastern Karni Crossing used only for cargo, and the other cargo crossing points, the Kerem Shalom Crossing on the border with Egypt and the Sufa Crossing farther north.

The wall featured about 300 towers, most of them now entirely or largely ruined.
WThe Korean Demilitarized Zone is a strip of land running across the Korean Peninsula. It is established by the provisions of the Korean Armistice Agreement to serve as a buffer zone between North Korea and South Korea. The demilitarized zone (DMZ) is a border barrier that divides the Korean Peninsula roughly in half. It was created by agreement between North Korea, China and the United Nations Command in 1953. The DMZ is 250 kilometres long, and about 4 kilometres wide.

WThe Uzbekistan–Kyrgyzstan barrier is a border barrier built by Uzbekistan along its border with Kyrgyzstan to prevent terrorist infiltration. Construction began in 1999 after bomb attacks in the Uzbek capital of Tashkent were blamed on Islamic terrorists originating from Kyrgyzstan. The fence, unilaterally erected in disputed territory has caused economic hardships in the poor agricultural areas of the Ferghana Valley and has separated many families in this traditionally integrated border region.

WThe Line of Contact separated the Armenian forces and the Azerbaijan Armed Forces since the First Nagorno-Karabakh war. It was formed in the aftermath of the May 1994 ceasefire that ended the First Nagorno-Karabakh War (1988–94). The mountain range of Murovdag is the northern part of the line of contact and is essentially a natural border between the two forces. The length of the line of contact was between 180 kilometres (110 mi) and 200 kilometres (120 mi) until 2020. It was slightly changed for the first time since the 1994 ceasefire during the Nagorno-Karabakh conflict of 2016, and aspects of the current line of contact since the 2020 ceasefire following Second Nagorno-Karabakh War remain unclear.
WThe Oman–United Arab Emirates border consists of three non-contiguous sections totalling 609 km in length.
WThe Saudi–Yemen barrier is a physical barrier constructed by Saudi Arabia along part of its 1,800-kilometer (1,100 mi) border with Yemen.

WTegart's Wall was a barbed wire fence erected in May-June 1938 by British Mandatory authorities in the Upper Galilee near the northern border of the territory in order to keep militants from infiltrating from French-controlled Mandatory Lebanon and Syria to join the 1936–1939 Arab revolt in Palestine. With time the security system further included police forts, smaller pillbox-type fortified positions, and mounted police squads patrolling along it. It was described as an "ingenious solution for handling terrorism in Mandatory Palestine."
