Armenia sits landlocked between Georgia, Azerbaijan, Turkey, and Iran in the South Caucasus. The country spans 29,743 square kilometers, making it smaller than Belgium. Mount Aragats reaches 4,090 meters, the highest point within modern Armenian borders. Mount Ararat, the national symbol visible from Yerevan on clear days, stands across the border in Turkey at 5,137 meters. The elevation ranges from 390 meters in the Debed River valley to alpine zones above 3,000 meters. Lake Sevan sits at 1,900 meters elevation, one of the largest high-altitude freshwater lakes globally, covering approximately 1,240 square kilometers depending on seasonal variation. The Lesser Caucasus Mountains run through the country, creating a landscape where 76.5% of terrain exceeds 1,000 meters elevation.
Yerevan operates as both capital and economic center, holding roughly one-third of Armenia's population of approximately 2.9 million. The city dates to 782 BC based on the cuneiform inscription at Erebuni Fortress, making it older than Rome by 29 years. Republic Square anchors the downtown with Soviet-era architecture in pink and yellow tufa stone. The Cascade Complex rises 572 steps from Tamanyan Street to the hillside neighborhood of Victory Park, incorporating the Cafesjian Center for the Arts inside the structure. Yerevan Metro operates two lines with ten stations, opened in 1981. Zvartnots International Airport handles approximately 3.5 million passengers annually pre-pandemic. Gyumri, the second city with around 113,000 residents, sustained an earthquake in 1988 that killed an estimated 25,000 people across the region and left parts of the city still under reconstruction.
The Armenian Apostolic Church claims status as the world's oldest state church, with King Tiridates III declaring Christianity the state religion in 301 AD, predating the Roman Empire's formal adoption. Etchmiadzin Cathedral, built starting in 303 AD, functions as the mother church and residence of the Catholicos. Geghard Monastery incorporates chambers carved directly into the Azat River gorge cliffs, with construction beginning in the fourth century and major expansions in the thirteenth century. Khor Virap monastery sits 100 meters from the Turkish border with Mount Ararat as backdrop, built over the pit where Gregory the Illuminator was imprisoned for 13 years before converting King Tiridates III. Tatev Monastery occupies a basalt plateau edge in Syunik Province, accessible since 2010 by the Wings of Tatev aerial tramway, which held the Guinness record for longest non-stop double-track cable car at 5,752 meters. Garni Temple remains the only standing Greco-Roman colonnaded building in the former Soviet Union, constructed in the first century AD and restored after a 1679 earthquake.
The Matenadaran in Yerevan holds approximately 23,000 manuscripts and 300,000 archival documents, including the earliest surviving Armenian parchment from the fifth century. Mesrop Mashtots invented the Armenian alphabet in 405 AD, creating 36 original letters that expanded to 38 by the thirteenth century. The repository contains manuscripts in Armenian, Greek, Arabic, Persian, Hebrew, Latin, and other languages covering theology, history, medicine, cosmology, and literature. The building opened in 1959, designed by architect Mark Grigoryan with a statue of Mashtots at the entrance. UNESCO inscribed the collection in the Memory of the World Register in 1997.
Lake Sevan experiences ecological pressure from Soviet-era water diversion that lowered the lake level by approximately 20 meters between 1933 and 2001. The government reversed policy and the lake has risen approximately 3 meters since. The lake contains a single native fish species, the endangered Sevan trout known locally as ishkhan. Sevanavank monastery sits on what became a peninsula after the water level drop, originally constructed on an island in 874 AD. The lake freezes partially in winter, with ice thickness reaching 70 centimeters in severe years. Four rivers feed the lake, with the artificial Hrazdan-Sevan tunnel and Arpa-Sevan tunnel supplementing natural inflow since the 1980s. The Hrazdan River forms the sole outflow, descending toward Yerevan and eventually to the Arax River.
