Church of St. Nicholas, Neoclassical church at Askold's Grave, Kyiv, Ukraine.

Church of St. Nicholas is a neoclassical church building with symmetrical proportions, white columns, and a central dome located at Askold's Grave. The structure displays the clean geometric forms and balanced facade design typical of neoclassical architecture.

The building was designed by Andrey Melensky, who served as Kyiv's city architect starting in 1799 and shaped urban development. The church was built during a period when neoclassical structures were modernizing the city's appearance and establishing new architectural standards.

The church is named after Saint Nicholas, the name Prince Askold took at his baptism in 867. Since 1992 it has belonged to the Ukrainian Greek Catholic Church, and since 1998 a lower church dedicated to Pope Saint Sylvester has operated in the semi-basement. Pope John Paul II visited it in 2001 during his trip to Ukraine.

The church stands in the Askold's Grave park on a slope above the Dnipro, reached on foot from the metro or along the park paths. The lower level holds a second church dedicated to Pope Sylvester, so visitors should look for the stair down as well as the main rotunda. The building is an active Greek Catholic parish, so entry may be restricted during services.

The church stands on the site of a wooden predecessor whose oldest depiction, with three domes, appears on Athanasius Kalnofoyskyi's 1638 plan of Kyiv. In 1847 the building was slated for demolition for a road to the Chain Bridge, but Emperor Nicholas I visited on 10 September and forbade it, saying it did not threaten to collapse and only needed repairs; a plaque with the phrase was later hung inside.
