The Kalyazinsky Observatory ("Kalyazinsky Point of Space Communications") was put into operation in 1992, at the peak of the collapse of science in the newly "abolished" Soviet Union and was officially intended to study the physics of pulsars, as well as galactic and extragalactic objects. In 2010, a serious fire occurred in the observatory, which destroyed a large part of the equipment and seriously damaged the main antenna - restoration work was carried out under the Federal Space Program and took about two years. The diameter of the main dish of the telescope is 64 meters, with a total mass of 3,800 tons (mirror mass 800 tons). Tourists' access to the site is closed, but you can admire the giant telescope from the outside and take very spectacular photographs.
