The cathedral was built to honor the 200,000 Russian soldiers who died in the Russo-Turkish War.
The interior contains 82 frescoes and 273 oil paintings executed by 32 Russian and 16 Bulgarian artists.
The gold leaf on the exterior domes was sourced from Germany and reapplied during several historical restoration projects.
The church's 12 bells have a combined weight of 23 tons, with the largest weighing 12 tons.
The floor is covered in multicolored Italian marble.
The underground crypt museum contains one of the largest collections of Orthodox Christian icons in Europe.
The cathedral's foundation stone was laid in 1882, but construction was delayed for decades due to funding and political issues.
St. Alexander Nevsky Cathedral is a Neo-Byzantine cross-domed basilica serving as the seat of the Bulgarian Patriarch. Completed in 1912 to commemorate the liberation of Bulgaria from Ottoman rule, it covers an area of 3,170 square meters. The central dome rises 45 meters high and features gold plating. The interior includes a crypt-turned-museum housing a significant collection of Orthodox icons and religious art. Its construction materials include marble from Siena, onyx from Brazil, and alabaster. The building's architecture combines Russian, Byzantine, and Bulgarian stylistic elements.
The view from the St. Sofia monument square provides the best angle for capturing the entire golden dome complex.
Visit the crypt museum located in the basement to view medieval Bulgarian icon art.
Walk around the perimeter to observe the varying detail of the mosaics and stone carvings.
Look for the smaller St. Sophia Church nearby, which predates the cathedral by centuries.
Do not attempt to photograph the interior during active church services as it is considered disrespectful.
The crypt museum is generally closed on Mondays. The main cathedral may have restricted entry during major religious holidays or official state ceremonies.
Visitors must dress modestly; shoulders and knees should be covered. Removing hats is required. Photography is strictly prohibited inside the main nave.
