The Assumption or Dormition Cathedral was the main Orthodox church of Kharkiv, Ukraine until the construction of the Annunciation Cathedral in 1901. The cathedral stands on the University Hill by the bank of the Lopan River and dominates the entire downtown. The Neoclassical cathedral bell tower, built in the 1820s and 1830s to a height of 90 meters, remained the tallest building in the city until the 21st century.
