Charentsavan was founded by the
Soviet government in 1948 as
Lusavan within the
Akhta raion (later renamed
Hrazdan raion in 1959) to accommodate the employees of the nearby hydroelectric power plant of Gyumush. With the completion of the power plant in 1953, the town became home to many industrial firms and turned into one of the vital industrial centres of the
Armenian SSR. Around 2/3rd of the town's economy was based on mechanical industries. In 1958, the reinforced concrete plant of Charentsavan was opened, followed by the machine-tools plant in 1959. In 1966, the "Kentronadzul" metal casting plant was opened to become the largest industrial firm of the town. 4 more factories were opened in the 1970s, including the "Lizin" chemicals plant in 1974, the "ArmAuto" metal structures and goods plant and "Bjni" water bottling plant in 1977, and the knitting plant in 1978. Several products of Charentsavan were delivered to the republics of the
Soviet Union. With the industrial growth of the town, the population had grown as well to reach up to 25,000 by the end of the 1970s. The major urban plan of the town designed by architects Avetik Mirijanyan and M. Safrastyan, was approved in 1971. It was envisaged to expand the town to accommodate a population of 65,000 by the end of the 20th century. The population of Charentsavan was in its peak in 1989 with around 33,000. However, with the
dissolution of the Soviet Union in 1991, many of the industrial plants were privatized and forced to reduce their capacities due to the economic recession. The population of the town dropped to 25,000 by the end of the 20th century. As per the 1995 administrative reforms, the Soviet raions were dissolved and the administrative provinces of Armenia were formed. Thus, Charentsavan became part of the newly-founded Kotayk Province. The town is roughly divided into 4 residential districts as well as a large industrial zone. The industrial district occupies around 70% of the entire area of Charentsavan. A large public park is situated between the industrial zone and the residential area. The town and the region are served by the state-owned Charentsavan Medical Center, operating since 1967 with a capacity of 300 beds. ==Geography and climate==
