The ruined Nikolskaya church in Buzuluk was located at the site of the modern Nikolsky garden, previously known as Pionersky, at the intersection of Oktyabrskaya and Maxim Gorky streets. This place holds special significance in the history of the city. Soon after the establishment of the Buzuluk fortress by I.K. Kirilov in 1736, near the confluence of the Buzuluk and Samara rivers, the fortifications were moved to the current hospital complex on Pervomayskaya street. After the fire of 1785, the fortress was not restored, and the city began to be built according to a new plan.

The new administrative and religious center of Buzuluk was established in the area of the present Nikolsky garden. In 1791, a church in honor of Archangel Michael with a chapel of Nicholas the Wonderworker was built here. Between 1824 and 1837, Emperor Alexander I and the future Emperor Alexander II visited this place. In 1835, a new city plan was approved by Emperor Nicholas I. In 1847, the Trinity Cathedral was built, becoming a new architectural dominant, and the center of the city shifted to the area of the modern Trinity Park. However, the old center continued to develop. At the initiative of Major N.G. Tikhonovsky and the project of architect K.A. Ton, the author of the Cathedral of Christ the Savior in Moscow, a new church was built. Emperor Nicholas I approved the project, and on May 9, 1851, the church was laid, and on September 30, 1860, it was consecrated.

The snow-white five-domed building with a semicircular apse was surrounded by a wrought-iron fence on a stone foundation. Inside the fence was a priest's burial site. The Nikolskaya church served as a parish church for the residents of the nearby streets, and its parish numbered several thousand people. The church was warm and located next to the old wooden church of the 18th century, which was moved to the Fair Square in 1862. In 1922, valuable items were removed from the church, and on July 17, 1932, local authorities decided to dismantle the building to use the bricks for the construction of a factory in Orsk. Dismantling began on February 15, 1933, but the bricks could not be preserved. Our ancestors built for centuries.

After the war, a Pioneers' garden was arranged at the site of the church, now known as Nikolsky. In the early 2000s, a cross and a memorial stone with a commemorative plaque were installed there.
