Armenia is a landlocked nation situated in the South Caucasus, positioned at the intersection of Western Asia and Eastern Europe. It shares borders with Turkey to the west, Georgia to the north, Azerbaijan to the east, and Iran and the Azerbaijani exclave of Nakhchivan to the south. Historically, the territory of Armenia once extended from the Black Sea to the Caspian Sea and from the Mediterranean Sea to Lake Urmia. The modern republic occupies a high-altitude plateau characterized by a mountainous landscape with an average elevation of approximately 1,800 meters. The geography is defined by the Lesser Caucasus mountain range and extinct volcanic peaks, most notably Mount Aragats, the highest point at 4,090 meters.

The administrative and economic heart of the country is Yerevan, which stands as one of the world's oldest continuously inhabited cities. Founded in 782 BC as the fortress of Erebuni by King Argishti I of Urartu, Yerevan predates Rome by 29 years. The city’s architecture is famously characterized by the extensive use of pink tuff, a volcanic stone that gives the central district a distinct hue. As a unitary multiparty republic, Armenia operates under a parliamentary system where the Prime Minister serves as the head of government and the President serves as the head of state. The legislative branch consists of the National Assembly, which currently manages the country’s legal and political frameworks.

Armenia holds the historical distinction of being the first nation to adopt Christianity as its state religion, a transition that occurred in 301 AD under King Tiridates III. This religious legacy is central to the national identity, with the Armenian Apostolic Church remaining the primary spiritual institution. The country is home to numerous UNESCO World Heritage sites, including the monasteries of Haghpat and Sanahin, and the cathedral and churches of Echmiadzin. These structures represent the evolution of Armenian ecclesiastical architecture, which influenced medieval European design. The Holy See of Echmiadzin remains the administrative center of the global Armenian Church and houses artifacts of significant religious importance.
