Church of the Ascension, Belgrade, Serbian Orthodox church building in downtown Belgrade, Serbia

The Church of the Ascension is a Serbian Orthodox church building in downtown Belgrade, distinguished by black Hungarian marble steps at its entrance. The structure occupies an entire city block bounded by four surrounding streets in a busy central area.

Construction was ordered in 1860 by Prince Miloš Obrenović and Metropolitan Mihailo, and the church was consecrated in March 1863, funded largely by citizens' donations. It served as a military church until 1866. In April 1940 the largest bell fell and killed the boy ringing it. German bombing in 1941 and Allied bombing in 1944 heavily damaged the church and killed many people.

The church is dedicated to the Ascension, called Spasovdan in Serbian, which is also the official slava of Belgrade. Each year after the liturgy a procession sets out from the church through the city streets and returns to its courtyard, closing the circle. The custom recalls 1403, when Despot Stefan Lazarević made Belgrade the Serbian capital on that day.

The church stands at Admirala Geprata 19, within the block also bounded by Kneza Miloša, Kraljice Natalije and Dobrinjska. The entrance is up the steps of black Hungarian marble. The churchyard trees were cut in 2013 after the communal inspection found them rotten.

The bell still rung here is the one under which the Hatisheriff of 1830 was proclaimed at Tašmajdan, granting Serbia autonomy within the Ottoman Empire. It was first kept in the Cathedral Church of St. Michael the Archangel and now swings by an electric mechanism.
