In the 18th century, Putivl was enriched with several outstanding churches, among which the Church of St. Nicholas the Cossack holds a special place. This temple was built with the funds of the Putivl Cossacks and is distinguished by its elegant two-towered silhouette, visible from afar. However, the true grandeur of the ancient architect's design becomes apparent only upon closer inspection.

Originally, the church was constructed between 1735 and 1737 as a three-part, single-domed structure. Later, in 1770, a multi-tiered bell tower was added to the western side of the church, altering the original silhouette of the building. The church consists of two floors. The first floor, known as the undercroft, housed a warm church where services were held in winter. The low vaults with their arches and abundance of light create an atmosphere of homely comfort. The upper part, called the cold church, was intended for summer services. Through an arch, one can see the high central dome, the edges of which create the illusion of unattainable height.

The church was created by a Russian architect, as confirmed by its structural features. However, since the client was the Ukrainian Cossack community of Putivl, the master was offered a Ukrainian wooden single-domed church as a model. The architect not only magnificently accomplished the task, creating a building with expressive proportions and silhouette, but also subtly considered visual perception: the windows of the first tier, at eye level, are adorned with exquisite moldings, while the windows above human height are devoid of decorations.

The Church of St. Nicholas the Cossack is an outstanding monument of Ukrainian Baroque architecture, demonstrating how professional architecture developed under the influence of folk traditions and tastes. Until recently, the church housed an exhibition of the museum 'The Tale of Igor's Campaign.'
