Klin is first mentioned in the Nikon chronicle in 1317, when is was the part of fortress cities, located at Volga tributary streams. Klin fortress was located on a high peninsula, surrounded by the river Sestra. In 1492 the settlement joined the Moscow princedom (Moscovia). Later it was known as the patrimonial estate of Romanov family. Peter the Great employed almost all citizens of Klin as coachmen, since the town waslocated between the old and the new capitals of Russia.

Most ancient architectural monument of Klin was the four-column single-dome Uspenskaya church with rowlock portals and unique gable curtain walls, which was erected in the 16 ^th century. Westwards from the Uspenskaya church one can admire the Voskresenskaya church, built in Moscow Baroque style in 1712, and the free standing hip-roofed bell tower, built in 1769 and dominating the town ever since. In 1781 Klin became the district town on the Moscow region.

General development plan, approved in 1784, gave Klin orthographic structure. The town acquired new administrative and other buildings in classic style, Empire style and “Russian” style.

In 1851 Klin was pierced by Nikolaevskaya railroad, connecting St. Petersburg and Moscow. The railroad provided perfect conditions for industrial development of the region. Coachmen started experiencing financial difficulties. In 1897 the ironworks was built near the railway station. Later a ribbon plant appeared. By the end of the 19 ^th century the town and its suburbs acquired 8 large plants and works, including cotton-spinning plant, ironworks, tanyard, crystal and glass works and a brick plant. Then former Demianovo estate also entered Klin. The estate included already mentioned Uspenskaya church, two-storey Early Classicism house and two parks. The estate was owned by Russian philosopher Taneev, who was friends with famous Russian composers, scientists and writers.

In 1926 modern technologies invaded the town, and new plants were built for producing laboratory equipment and artificial fibre. During the Great Patriotic War (known as World War II) the town of Klin was occupied by fascist troops in 1941 and almost destroyed.

Klin is surrounded by very picturesque nature – nice hills, framed by green forests. Klin is tightly linked with names of many famous Russian persons of science and culture: artists V. Perov and A. Korin, sculptress Vera Mukhina, writer Mikhail Prishvin and many others. Former Boblovo estate, located near Klin, hosted great Russian scientist – world-famous chemist Dmitry Mendeleev, who lived there from 1865 until 1906. In August 1887 the chemist performed a balloon ride in order to observe a sun eclipse.

Another attraction for tourist is located 16 km northwest from Klin in the Beresino village. It is a wooden Nikolskaya church of cage type, which was built in 1775.

Modern Klin is one of industrial centres of the Moscow Region. The city shelters about 100 thousand of citizens.
