The Vordan Karmir Sanctuary is the only protected natural area in the province. It is home to the Armenian cochineal, an insect that formerly used to produce an eponymous crimson carmine dyestuff known in Armenia as vordan karmir. The red dye of the insect was largely used in Armenian miniatures as well as other types of artworks throughout the history of ancient and medieval Armenia. 
The province is named after the ancient city of Armavir founded in 331 BC. The province is also the site of the decisive Battle of Sardarabad in 1918 that resulted in the foundation of the Republic of Armenia. The battle is seen as a crucial historical event not only by stopping the Turkish advance into the rest of Armenia but also preventing the complete destruction of the Armenian nation. So here is located the Sardarapat Memorial (1968) commemorating the Battle of Sardarapat.
The Metsamor Nuclear Power Plant is also located in Amravir Province near the town of Metsamor.

Saint Hripsime Church

Saint Hripsime Church is a seventh century Armenian Apostolic church in the city of Vagharshapat (Etchmiadzin). It is one of the oldest surviving churches in the country. The church was erected by Catholicos Komitas atop in the place of the original mausoleum built by Catholicos Sahak the Great in 395 AD, that contained the remains of the martyred Saint Rhipsime (Hripsime) to whom the church was dedicated.

For them 3 churches were bulit St. Hripsime, St. Gayane (630) and Shoghakat(1694),which are listed as UNESCO world heritage sites.

Zvartnots Cathedral

Zvartnots Cathedral (meaning "celestial angels") is a 7th-century centrally planned aisled tetraconch type Armenian cathedral built by the order of Catholicos Nerses the Builder. Now in ruins, it is located at the edge of the city of Vagharshapat (Etchmiadzin) in Armavir Province of Armenia. According to the medieval Armenian historian Movses Kaghankatvatsi, the cathedral was consecrated in 652. From 653 to 659, Nerses was in Tayk and the construction of the cathedral continued under Anastas Akoratsi. Following the Arab occupation of Dvin and the intensifying wars between the Byzantine and Arab armies on the former's eastern borders, Nerses transferred the patriarchal palace of the Catholicos from Dvin to Zvartnots. The ruins of Zvartnots remained buried until its remains were uncovered at the start of the 20th century. The site was excavated between 1901 and 1907 under the direction of vardapet Khachik Dadyan, uncovering the foundations of the cathedral as well as the remains of the Catholicos palace and a winery.

Etchmiadzin Cathedral

Etchmiadzin Cathedral is the mother church of the Armenian Apostolic Church, located in the city of Vagharshapat (Etchmiadzin). 
According to most scholars, it was the first cathedral built in ancient Armenia, and is considered 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. It replaced a preexisting temple, symbolizing the conversion from paganism to Christianity. The core of the current building was built in 483/4 by Vahan Mamikonian after the cathedral was severely damaged in a Persian invasion. From its foundation until the second half of the fifth century, Etchmiadzin was the seat of the Catholicos, the supreme head of the Armenian Church.
