What is the Purpose of an Embassy?
An embassy aims to connect two nations and to demonstrate dialogue between them. If an embassy is enclosed by high walls and appears as an impenetrable fortress, the dialogue it represents is full of mistrust. Conversely, if it is transparent and open, it reflects a relationship based on trust (Ahmadi, 2007). Despite the importance of urban planning and architecture in embassies and other diplomatic buildings, our knowledge about them is very limited. Access to these places—often secluded and hidden—is usually through controlled pathways and interactions with staff behind security desks. Only a few architects are familiar with their functions, technical requirements, structural characteristics, and other features. These buildings are particularly fascinating from a design perspective due to their complexity and their interaction with multiple nationalities and cultures. Moreover, most countries pay careful attention to the architecture of their diplomatic missions abroad, as designing them offers an opportunity to enhance architectural quality in terms of design, technical specifications, and building standards. Diplomatic relations between governments date back to ancient times (Afshari-Naderi, 2009, p. 4).

What is an Embassy?
An embassy is the office of a country’s diplomatic representatives in another country. The main office, usually located in the capital, is called the embassy, while offices in other cities are referred to as consulates. Consulates generally do not provide all the services available at the main embassy (Razavinasab & Zakari, 2015).

Dictionaries define an embassy as: a place where the ambassador and their staff carry out political duties related to their country; a residence where the diplomatic mission performs political functions; the home of the ambassador (Dehkhoda Dictionary, 1998; Amid Dictionary, 2010).

History of Embassies
Until the 17th century, international relations were generally conducted through direct correspondence between rulers or through envoys and ambassadors sent for specific purposes. This method often produced unsatisfactory results, as many ambassadors faced difficulties while delivering their sovereign’s orders. By the late 17th century, permanent embassies had become common in Europe. Due to disputes over titles, precedence, and the hierarchy of political officers, the Congress of Vienna (1815) classified diplomatic staff. This classification was later revised and accepted by major states. Diplomats in the countries where they were posted enjoyed various immunities and privileges, including exemption from taxes, arrest, or legal prosecution. Their residences were considered extraterritorial, and these benefits were later extended to all embassy staff.

Diplomats are tasked with observing political, economic, and military events in accordance with international norms—without resorting to espionage—and reporting accurate information to their home government. They are generally accountable to their country’s foreign ministry and interact primarily with the host country’s foreign ministry, conducting their work through official notes. Diplomacy has its own specialized language and terminology, and until recently, French was the standard language of diplomacy. While some countries maintain distinctions between diplomatic and consular roles, in most countries these differences have largely disappeared (Razavinasab & Zakari, 2015).

The first permanent ambassadors were sent by the Vatican to the Byzantine Empire in Istanbul (8th century). Modern diplomacy emerged during the Renaissance, although some permanent embassies were established in Europe as early as the 13th century. In the 13th century, representatives from the Genoese Empire were permanently present in Tabriz. Many modern diplomatic traditions developed in 14th- and 15th-century Italy.

In Iran, modern foreign embassies emerged in the first half of the 19th century. Among the oldest in Tehran are the embassies of Russia, France, the United Kingdom, Germany, and Italy. These historic buildings and gardens, often maintained due to the continuous presence of diplomatic missions, provide valuable insights into the city’s past. Currently, the embassies of Turkey, Germany, Russia, the UK, and Italy occupy extensive grounds that remain prominent features in Tehran’s urban landscape (Alpha Engineering Associations, 2013)

I have designed an embassy project during my university studies, and I would like to share it with you through the following links.
