Armenia, the first Christian country in world, has a lot to offer if you want to visit old churches and monasteries.
The following sites are in the UNESCO World heritage list:
Monastery of Haghpat and Sanahin — 1996
Cathedral and Churches of Echmiadzin and the Archaeological Site of Zvartnots — 2000
Monastery of Geghard and the Upper Azat Valley — 2000
The country’s nature stuns visitors with its mountainous beauty. Perhaps the most well-known site is Lake Sevan, the world’s largest mountain lake. The Tsakhkadzor ski resort, open for skiing in the winter and hiking and picnicking the rest of the year, is well worth a visit.
Yerevan (Armenian: Երևան [jɛɾɛˈvɑn]) is the capital and largest city of Armenia and one of the world's oldest continuously inhabited cities. Situated along the Hrazdan River, Yerevan is the administrative, cultural, and industrial center of the country. It has been the capital since 1918, the thirteenth in the history of Armenia. The history of Yerevan dates back to the 8th century BC, with the founding of the fortress of Erebuni in 782 BC by king Argishti I at the western extreme of the Ararat plain. After World War I, Yerevan became the capital of the Democratic Republic of Armenia as thousands of survivors of the Armenian Genocide settled in the area. The city expanded rapidly during the 20th century as Armenia became one of the fifteen republics in the Soviet Union. In fifty years, Yerevan was transformed from a town of a few thousand residents within the Russian Empire, to Armenia's principal cultural, artistic, and industrial center, as well as becoming the seat of national government. With the growth of the economy of the country, Yerevan has been undergoing major transformation as many parts of the city have been the recipient of new construction since the early 2000s, and retail outlets such as restaurants, shops and street cafes, which were rare during Soviet times, have multiplied. As of 2011 estimates, the population of Yerevan was 1,121,900 people making up to 34% of the total population of Armenia. Yerevan was named the 2012 World Book Capital by UNESCO.
Armenia (ɑrˈmiːniə/ Armenian: Հայաստան Hayastan), officially the Republic of Armenia (Armenian: Հայաստանի Հանրապետություն, Hayastani Hanrapetut’yun), is a mountainous country in the South Caucasus region of Eurasia. Located at the crossroads of Western Asia and Eastern Europe, it is bordered by Turkey to the west, Georgia to the north, the de facto independent Nagorno-Karabakh Republic and Azerbaijan to the east, and Iran and the Azerbaijani exclave of Nakhchivan to the south. Armenia is a unitary, multi-party, democratic nation-state with an ancient cultural heritage. The Kingdom of Armenia was established in the 6th century BC, after the fall of Urartu; it became the first state in the world to adopt Christianity as its religion, in the early years of the 4th century (the traditional date is 301 AD). The modern Republic of Armenia recognizes the Armenian Apostolic Church, the world's oldest national church, as the country's primary religious establishment. Armenians have their own unique alphabet invented by Mesrop Mashtots in 405 AD. Ethnic Armenians make up 97.9% of the population. Yazidis make up 1.3%, and Russians 0.5%. Other minorities include Assyrians, Ukrainians, Greeks, Kurds, Georgians, and Belarusians. There are also smaller communities of Vlachs, Mordvins, Ossetians, Udis, and Tats. Minorities of Poles and Caucasus Germans also exist though they are heavily Russified.
