The Friedhofskirche (cemetery church) of St. Constantine and St. Helena was built in 1894 and is…read morethe oldest of the Russian Orthodox churches in Berlin. The Berlin-Tegel Russian Orthodox Cemetery is the only Russian Orthodox burial ground in Berlin. I like the church a lot, it's very peaceful and heartwarming, the cemetery is taken care of. Lot's of old graves from the First World War and even older can be found here. The church has its quite big and strong parish.
