Alexander Nevsky Cathedral, Sofia, Bulgaria

The St. Alexander Nevsky Cathedral in Sofia occupies an area of 3,170 square metres (34,100 sq ft) and can hold 5,000 people inside. It is one of the largest Eastern Orthodox Cathedrals and church buildings in the world.

The Alexander Nevsky Cathedral is a cross-domed basilica featuring an emphasized central dome.

The construction of the St. Alexander Nevsky Cathedral started in 1882 (having been planned since 19 February 1879), when the foundation stone was laid, but most of it was built between 1904 and 1912. Saint Alexander Nevsky was a Russian prince. The cathedral was created in honour 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.
