Stary Biser

Stary Biser was founded in 1787 during the construction of an iron foundry that existed to the beginning of the 20th century. In the 1920s it was used as a basis for a shop of the shaped iron casting of the Teplogorsk Casting and Mechanical Plant.^[5]

In the settlement, there are two sites of the Biser Teplogorskiy factory (17th–19th century) and a house where the prominent activist of the RSDLP(b) Sergeyev lived.

In 1926, owing to the full exhaustion of local mines, the melting of pig-iron at Biserka metallurgical plant was stopped, and the plant itself was closed.

An urban-type settlement from 27 August 1928.
