The Alexander Nevsky Cathedral is a stunning orthodox cathedral located in the capital city of Estonia, Tallinn. The cathedral was completed in 1900 and was named after Alexander Nevsky, a Russian saint and military leader. The building is notable for its distinct architectural style, which is a combination of traditional Russian and Byzantine elements. The interior of the cathedral is equally impressive, with intricate murals, gilded decorations, and colorful mosaics.

The cathedral was controversial from the beginning due to its location in the center of Tallinn's Old Town. Many Estonians saw the cathedral as a symbol of Russian oppression, and its construction was seen as an attempt by the Russian Empire to assert its dominance over Estonia. Despite this, the cathedral has become an important landmark in Tallinn and is now recognized as one of the city's most iconic structures.

Today, the Alexander Nevsky Cathedral is open to visitors and remains an active place of worship for the local Russian Orthodox community. Visitors can marvel at the cathedral's impressive architecture and explore its rich history through guided tours and exhibits. The cathedral is also known for its renowned choir, which performs regular concerts and recitals.
