The history of the city of Kolpino is inextricably linked to the industrial reforms of Peter the Great and the founding of Saint Petersburg. The date of its foundation is considered to be 1722, when, by decree of the Tsar, the construction of a sawmill began on the Izhora River to meet the needs of the burgeoning fleet and the new capital. A worker settlement quickly grew around this enterprise, marking the beginning of the future city. The main engine of Kolpino's development and its key enterprise became the Izhora Plants, which grew out of Peter's sawmill. They quickly evolved into one of Russia's leading industrial complexes, specializing in metallurgy, mechanical engineering, and the fulfillment of critical state orders, ensuring steady growth and an influx of population.
From the very beginning, Kolpino was shaped as an industrial center, its life entirely dictated by the rhythm of factory work. For its time, the settlement possessed a developed social infrastructure: the plants operated their own hospital and school. Along with Russian craftsmen, foreign specialists, including Finns and German colonists, worked at the Izhora Plants, contributing to its culture and production. A significant boost for economic growth was the opening in 1847 of a station on the Nikolaevskaya (now Oktyabrskaya) Railway, which greatly improved communication with Saint Petersburg and other regions. Kolpino officially received city status in 1912, solidifying its role as an important industrial satellite of the empire's capital.
