Built in Neo-Byzantine style between 1904 and 1912, it serves as the cathedral church of the Patriarch of Bulgaria and is one of the largest Eastern Orthodox cathedrals in the world, as well as one of Sofia's symbols and primary tourist attractions. The St. Alexander Nevsky Cathedral in Sofia occupies an area of 3170 m² and can take 5,000 people inside.

The cathedral stands as a memorial to the Russian soldiers who died during the Russo-Turkish War of 1877-1878, as a result of which Bulgaria was liberated from Ottoman rule.
