I thought these were two different churches but i was wrong, these are two different views of the St. Alexander Nevsky Cathedral in Sofia, Bulgaria. The 1st card was sent by Christina "dj_christina" and the 2nd by Lilia "childish". Both were favorite cards.
The St. Alexander Nevsky Cathedral is a Bulgarian Orthodox cathedral in Sofia, the capital of Bulgaria. Built in Neo-Byzantine style, 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 3,170 square metres (34,100 sq ft) and can hold 10,000 people inside. It is the biggest cathedral located on the Balkan Peninsula.
The construction of the St. Alexander Nevsky Cathedral started in 1882, 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. - in: wikipedia
