TurkeyTurkey (Türkiye, ˈtyɾcije), officially the Republic of Türkiye (Türkiye Cumhuriyeti ˈtyɾcije dʒumˈhuːɾijeti), is a country located mainly on the Anatolian Peninsula in West Asia, with a small portion on the Balkan Peninsula in Southeast Europe. It borders the Black Sea to the north; Georgia to the northeast; Armenia, Azerbaijan, and Iran to the east; Iraq to the southeast; Syria and the Mediterranean Sea to the south; the Aegean Sea to the west; and Greece and Bulgaria to the northwest. Cyprus is off the south coast.
Vault (architecture)In architecture, a vault (French voûte, from Italian volta) is a self-supporting arched form, usually of stone or brick, serving to cover a space with a ceiling or roof. As in building an arch, a temporary support is needed while rings of voussoirs are constructed and the rings placed in position. Until the topmost voussoir, the keystone, is positioned, the vault is not self-supporting. Where timber is easily obtained, this temporary support is provided by centering consisting of a framed truss with a semicircular or segmental head, which supports the voussoirs until the ring of the whole arch is completed.
Etchmiadzin CathedralEtchmiadzin Cathedral (Ēǰmiatsni mayr tačar) is the mother church of the Armenian Apostolic Church, located in the city dually known as Etchmiadzin (Ejmiatsin) or Vagharshapat, Armenia. It is usually considered the first cathedral built in ancient Armenia, and often regarded the oldest cathedral in the world. The original church was built in the early fourth century—between 301 and 303 according to tradition—by Armenia's patron saint Gregory the Illuminator, following the adoption of Christianity as a state religion by King Tiridates III.
VagharshapatVagharshapat (Վաղարշապատ vɑʁɑɾʃɑˈpɑt) is the 4th-largest city in Armenia and the most populous municipal community of Armavir Province, located about west of the capital Yerevan, and north of the closed Turkish-Armenian border. It is commonly known as Ejmiatsin (also spelled Echmiadzin or Etchmiadzin, Էջմիածին, ɛt͡ʃhmjɑˈt͡sin), which was its official name between 1945 and 1995. It is still commonly used colloquially and in official bureaucracy (dual naming).
ArmeniaArmenia, officially the Republic of Armenia, is a landlocked country in the Armenian Highlands of West Asia, with geopolitical ties to Europe. It is a part of the Caucasus region and is bordered by Turkey to the west, Georgia to the north and Azerbaijan to the east, and Iran and the Azerbaijani exclave of Nakhchivan to the south. Yerevan is the capital, largest city and financial center. Armenia is a unitary, multi-party, democratic nation-state with an ancient cultural heritage.
KarsKars (Կարս or Ղարս; Qars; Qers) is a city in northeast Turkey. It is the seat of Kars Province and Kars District. As of 2022, its population was 91,450. Kars, in classical historiography (Strabo), was in the ancient region known as Chorzene (Χορζηνή), part of the province of Ayrarat in the Kingdom of Armenia, and later the capital of the Bagratid Kingdom of Armenia from 929–961. Currently, the mayor of Kars is Türker Öksüz. The city had an Armenian ethnic majority until it was re-captured by Turkish nationalist forces in late 1920.
Byzantine architectureByzantine architecture is the architecture of the Byzantine Empire, or Eastern Roman Empire. The Byzantine era is usually dated from 330 AD, when Constantine the Great established a new Roman capital in Byzantium, which became Constantinople, until the fall of the Byzantine Empire in 1453. However, there was initially no hard line between the Byzantine and Roman Empires, and early Byzantine architecture is stylistically and structurally distinguishable from earlier Roman architecture.
KhachkarA khachkar (also spelled as khatchkar) or Armenian cross-stone (խաչքար, χɑtʃhˈkhɑɾ, խաչ xačʿ "cross" + քար kʿar "stone") is a carved, memorial stele bearing a cross, and often with additional motifs such as rosettes, interlaces, and botanical motifs. Khachkars are characteristic of medieval Christian Armenian art. Since 2010, khachkars, their symbolism and craftsmanship are inscribed in the UNESCO list of Intangible Cultural Heritage. The most common khachkar feature is a cross surmounting a rosette or a solar disc.
BasaltBasalt (UKˈbæsɔːlt,_-əlt; USbəˈsɔːlt,_ˈbeɪsɔːlt) is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year.
