Beirut is the capital and largest city of Lebanon. As of 2014, Greater Beirut has a population of 2.4 million, which makes it the third-largest city in the Levant region. The city is situated on a peninsula at the midpoint of Lebanon's Mediterranean coast. Beirut has been inhabited for more than 5,000 years, and was one of Phoenicia's most prominent city states, making it one of the oldest cities in the world (see Berytus). The first historical mention of Beirut is found in the Amarna letters from the New Kingdom of Egypt, which date to the 14th century BC.

Beirut is Lebanon's seat of government and plays a central role in the Lebanese economy, with many banks and corporations based in the city. Beirut is an important seaport for the country and region, and rated a Beta + World City by the Globalization and World Cities Research Network. Beirut was severely damaged by the Lebanese Civil War and the massive explosion in the Port of Beirut. Its cultural landscape underwent major reconstruction.

A diplomatic mission or foreign mission is a group of people from a state or organization present in another state to represent the sending state or organization officially in the receiving or host state. In practice, the phrase usually denotes an embassy, which is the main office of a country's diplomatic representatives to another country; it is usually, but not necessarily, based in the receiving state's capital city. Consulates, on the other hand, are smaller diplomatic missions that are normally located in major cities of the receiving state (but can be located in the capital, typically when the sending country has no embassy in the receiving state). As well as being a diplomatic mission to the country in which it is situated, an embassy may also be a nonresident permanent mission to one or more other countries.The term embassy is sometimes used interchangeably with chancery, the physical office or site of a diplomatic mission. Consequently, the term "embassy residence" and "embassy office" is used to distinguish between the ambassador's residence and the chancery.
