Today I got a nice postcard from Bulgaria! The postcard shows multiple views of different sites in Bulgaria, including the St. Alexander Nevsky Cathedral in Sofia, the Vitosha Mountain, and the Boyana Waterfall. The cathedral was completed in 1912 and is a Bulgarian Orthodox cathedral. It is the cathedral church of the Patriarch of Bulgaria and is one of the largest Eastern Orthodox cathedrals. It can accomodate up to 10,000 people and covers an area of about 3,000 square metres. Thanks Nadezhda!
